Mature Adult Discussion

  • 1.  Mature Adult Discussion

    Posted 08-09-2019 20:14
    I participate in the on-line discussion communities of three organizations of technical people: AIChE, NSPE (National Society of Professional Engineers), and Sigma Xi (The Scientific Research Honor Society).  They all use the same format (and, I assume, the same software) and they all have somewhat similar codes of conduct.  Sigma Xi interprets its code of conduct different than the other two in that it imposes much less censorship, indeed, almost no censorship, and, in my opinion, has discussions that are much more interesting to observe and are much more inviting for observers to join.  Engineers and scientists, like most adult professionals, want to be treated as such, and censorship above an absolute minimum suggests that we aren't mature enough to behave accordingly.  AIChE needs to rethink its censorship approach to recognize that its members are capable of civil discussion even on controversial topics.

    I've never been censored here. I'd hope that a professional engineering discussion group would be talking engineering topics and the only potential for censorship would be something along the lines of  posting company-sensitive or trade secret information. I'd be disappointed to find out that a forum like this might degenerate to where something like trolling or unprofessionalism would encroach on scientific and engineering assistance. That stuff can be taken to Reddit.

    Maybe some examples would be enlightening?

    See my response to the post by Victor Rice for recent examples of what I consider inappropriate censorship.

    We may disagree on the kinds of things about which people can post on AIChE Engage.  There are things that we might want to share with our fellow AIChE members that are not uniquely specific to chemical engineering.  Doing so promotes fellowship and may create friendships; and such things should be encouraged.

    This is my opinion. I do not believe that censorship played a role in what is perceived as ending the discussion on climate change which is such a divisive topic. There were enough views expressed and posted and it was time to move on to other chemical engineering issues! I commend the moderator for what was done.

    Re August 13 post by Fredesvinda Bonotan-Dura:
    Any thread addressing climate change in any way will eventually be reduced to the debunking of false claims challenging the anthropogenic global warming reality, a theory that meets all the requirement of being a valid scientific theory.  Since there are still people who have accepted and/or are being confused by the false claims but would think differently if they understood the evidence and the conclusions based on that evidence, the more the subject is discussed by competent knowledgeable people the more those who are confused will understand and be better able to comfortably accept the conclusions of the qualified climate professionals. These discussions promote learning and should be encouraged and supported.  AIChE is legally an educational institution and all kinds of legit1mate education should be promoted, especially that for which chemical engineers are especially qualified to receive.  Money driven politics has promoted confusion and denigrated valid climate science. As people of science we have almost a moral obligation to fully understand the realities of so important a topic as climate change and help educate our non-technical friends and neighbors.  AIChE Engage has been an excellent forum for clarifying misunderstandings in this area, but there still remains some that need to be addressed.  Shutting down meaningful public discussions of important topics is totally inconsistent with what AIChE should and is supposed to be.

    Hi, everyone. Todd Przybycien is one of the eight candidates for Director in this year's AIChE elections. I asked him to share his position on climate science and he gave me permission to post this on his behalf:

    "To your question on my position, it's straightforward: climate change is an existential threat. Climate scientists are faced with the challenge of the lack of a control system, making deconvolution of anthropogenic climate change from non-anthropogenic climate change imperfect. All science is imperfect and there will always be disagreements. Scientists develop the best models they can and early predictions have been consistent with our lived experience thus far. For me, the correlations of human activity with GHG levels are clear and I am familiar with Beer's law – and the work of the IPCC is compelling/alarming. AIChE's position statement is mild, and while mild statements can be broadly inclusive of member opinions, mild won't help us deal with whatever fraction of this threat over which we can still exert some control. Can AIChE partner with AAAS, NAS/NAE and other professional/technical organizations to help move us towards solutions? Can AIChE somehow help catalyze the necessary changes in industry/agriculture/society and build consensus, recognizing the current spectrum of individual and corporate opinions? I would hope so – if not us, who?"

    Thanks so much to the candidates who have shared their position.  We are still waiting to hear from five of the ten candidates:  Dr.  Gregory Frank, who is running for President-Elect, and Professor Bob Kelly, Dr. Ann Lee, Professor Douglas Clark, and Professor Linda Broadbelt, all of whom are running for Director.  Hopefully we will hear from all of them by September 9, which is when voting begins.  We will be electing the President-Elect and four Directors.

    In response to Neil's AS YET APPROVED post of 8/15, 10pm-

    Well Neil it appears the content you attempted to repost has been censored, again. You final observation, "I cannot imagine how that would violate any reasonable provision of the Code of Conduct.", prompted me to go read the Code of Conduct. From item 4: "The community is meant to stimulate conversation and trigger the exchange of information (technical, career-related) not to create contention. Contradictory opinions are of course welcomed, but should always be thoughtful and respectful, rather than emotional, impulsive or anger-driven (you'd be surprised, it happens)." From item 5: "AIChE Engage is a place to discuss chemical engineering, its related disciplines, professional development and education. It is not a discussion forum for politics or religion."

    While I think it unfortunate your message was deemed not in compliance (it's still not posted as of Fri morning), I can certainly see an interpretation of the Code that would cause your message to be censored. Labeling individuals in a way that has been explicitly stated to be offensive, by SOME, could certainly be judged as an act intended to create contention. This act could also be judged as "political" as opposed to a contribution intended to specifically argue the merits of your case. Again, my response is SO WHAT. But I'm not the moderator.

    At this point I am genuinely curious as to what goal of yours in this debate do you believe to be unattainable WITHOUT the act of labeling folks as a member of some group?

    Re August 16 post by Victor Rice:


    The Engage software sends a copy of each submission to everyone who has posted on the thread to which the submission is submitted, so you know that I tried to expand on an earlier post and I didn't know until reading your post that mine had gotten that far.  I know that it hasn't been posted.

    To answer your question  ...

    I wrote what I tried to post to explain to a contributor why he was being called a denier when he identified  himself a skeptic.  Mine was the second unsuccessful attempt to respond.  The first, by another frequent contributor to Engage, was simply to say that it didn't make a difference what a person (not accepting the reality of anthropogenic global warming) considered himself or herself to be because whether a skeptic or a denier the effect was the same, which was to work against taking meaningful action to address the problem of the possibly impending mass extinction.  All I was trying to do was to explain why those who are passionate about protecting humanity's future don't care how a person self identifies if that person's position supports a counterproductive movement. 

    Nobody has the right to deny to others the right to use the English language as it should be used because they do not like a particular word even when it is correctly used. 

    I started this thread comparing the approach Sigma Xi takes, one very different than that of AIChE, and, in my opinion, much better, with how AIChE monitors its blog.  Sigma Xi does not permit personal attacks of any kind but they allow almost anything that is honest, truthful, and sincere. They treat their members as the mature adults they are, and thereby make their blog far better than it otherwise would be.  Yes, sometimes people who post nonsense can get embarrassed when what they have posted is shown to be nonsense, but all that really does is discourage the posting of nonsense. 

    If this conversion were being held on the Sigma Xi blog at least one contributor would observe that if one doesn't want an unflattering label don't do anything that makes that label appropriate.

    I started this thread to try to improve AIChE, something I have been trying to do for about 30 years.  I have had some success but not nearly enough.

    Thank you, Kirsten, for keeping track.  I will not be voting for candidates who will not clarify their position on this all-important issue.

    I was very disappointed that my original thread on the AIChE Climate Policy Statement was shut down.  For no good reason, and the questions I asked were not resolved.  Will AIChE update its policy statement?  The present version is a travesty.

    I'm also disappointed that the various climate discussions devolved into arguments about whether climate science is valid.  In my opinion, that question is settled.  My children, currently in elementary school, will see major impacts of climate change in their lifetime.

    My core question is, what can we as chemical engineers do to reduce greenhouse gas emissions and limit the impact of climate change? And what can AIChE as the chemical engineering professional society do?

    We should all start working on this because there's not much time left.

    Hi, everyone.  Professor Bob Kelly is one of the 8 candidates for 4 director positions in the AIChE election this year.  He asked me to post this on his behalf:

    "I am absolutely concerned about climate change and have spent most of my career directing research to this end - e.g., CO2 capture by plants and microorganisms, bio-based chemicals from lignocellulose. This gives me an informed perspective on issues along these lines that every chemical engineer must confront. Climate change needs to be at the forefront of the profession of chemical engineering and I hope to be a leader in this regard (whether elected as a Director or not)."

    At this point we have information about the climate science position of six of the ten candidates.  I am hoping to hear from the remaining four before electronic voting begins on Monday.  I have uploaded a pdf of what we have so far.

    Thanks, Kirsten, for keeping track and compiling this information.

    I think this is extremely important to understand where leadership stands on important issues that may require the institute to work with partnerships, lobbying with different governments, and creating new centers in collaboration with industry, nonprofits, for profits, academia and other entities.

    At the end of the day, AIChE is OUR community and the direction of the involvement at the global scale is something we all have a voice and input within.  Engaging with the leadership candidates on these important issues is important as new initiatives are created and we look for the institute to become leaders in various areas.

    Marc de Mul asks, "What may we chemical engineers do ... ? "  Fortunately, several years ago AIChE embraced the Ammonia Fuel Association, now Ammonia Energy Association   www.ammoniaenergy.org     by including the latter's annual meeting as an adjunct to the AIChE annual meeting.  AIChE members should attend, join, or otherwise support global efforts to commercialize this important C-free  energy carrier and low-cost storage medium for CO2-emission-free (CEF) energy sources.  Also see Japan's interest in "Energy Carriers":  http://www.jst.go.jp/sip/pdf/SIP_energycarriers2015_en.pdf     As energy professionals and citizens, our urgent task is nothing less than near-total decarbonization of the human enterprise:  energy and manufacturing, including iron ore reduction, N-fertilizer, portland cement, and crude oil refining -- while it lasts.   We cannot, and should not try to, accomplish this via electricity systems alone, although "The Grid" and "electric cars" dominate the present conversation about responses to "climate change".  We must embrace H2 and NH3 as energy carriers, storage media, and decarbonization vectors as complete, integrated, optimized energy systems.
    See The Hydrogen Council:   hydrogencouncil.com        See the International Energy Agency (IEA) report on "The Future of Hydrogen"   www.iea.org/topics/hydrogen
    Surely ChemE's will be needed for this global energy transition, and should lead it:  we now need a collaboration among a large and diverse technical and economic community to inquire, " How shall the near-total decarbonization of the human enterprise be optimally -- technically and economically -- accomplished by a synergistic mix of electricity and chemical energy systems to gather, transmit, store, distribute, and deliver firm, dispatchable, energy services from diverse CEF sources, both centralized (big solar and wind plants) and distributed (local sources, such as rooftop PV) ? "  We need to prevent over-dependence on the electricity Grid:  over-investment in designing and building the Grid, recognizing that it fundamentally operates at light speed and is therefore especially vulnerable to cyberattack; electricity storage in batteries is too costly for annual-scale firming storage; above ground infrastructure is vulnerable to acts of God and man.  Energy systems, at local to continental to global scales, based on H2, NH3, and perhaps other molecules, may be technically and economically superior, in many situations.
    We cannot afford to waste resources barking up the wrong tree, trying to push a square peg into a round hole, slowing the urgent enterprise-wide transition away from CO2-emitting processes.  We need the help of ChemE's, in many ways.

    As a new member I find it heartening that senior members and fellows feel that these forums should be used to discuss not just technology improvements but reduction of greenhouse gas emissions. I agree with you that we are past discussions on the validity of climate science. Whatever your position is on that we can all agree that industry emissions can have direct negative effects on the environment and should be reduced regardless.

    Our professional and humanitarian goal, as professionals and citizens, should be near-total decarbonization of the entire human enterprise, as quickly as we prudently and profitably can.  Prudently:   we don't want to destroy civilization in the process.  Profitably:  the large amount of capital required will only flow to investments with attractive reward-to-risk ratios.

    I didn't realize that this discussion had been terminated by AIChE.  Why ?  Had it run its course, devolved into an ideological shouting match ?  How else forAIChE to advance the above goal ?

    I agree with your general idea Neil. Where I differ just a bit is on “civil” discussion. Our community is no more, and no less, capable of civil discussions than most other communities. And that’s just fine. The issue here is what is civil for one is insulting for another. I’ve seen numerous examples of this in the climate threads. Maybe in some cases it was intentional trolling. Hard to tell. But SO WHAT!! Some of these discussions are quite emotional, nay religious, to some. That should surprise no one. Some topics deserve the passion occasionally exhibited. I would certainly hope most in this community could continue to participate in a truly civil way in the face of these occasional, infrequent lapses into less civil language. And in the threads I’ve observed that’s exactly what occurred.
    I find it unacceptable that the very infrequent (IMHO) lack of civility can result in discussions being shutdown. Is this why the moderator just shutdown the Climate Policy discussion? I found this discussion VERY enlightening and was most disappointed it was shutdown. That I find just ridiculous. Maybe the moderator can enlighten us on why that occurred.
    So I definitely agree AIChE should rethink the moderator guidelines if in fact those guidelines resulted in the Climate Policy thread being shutdown.

    Re August 10 post by Victor Rice:


    You are correct in your assumption that my message is a result of some of the discussions in the thread on the AIChE policy statement on climate change.  It is, indeed, a topic that can generate passion and different people have different ways of expressing it.  It needs to be understood and acknowledged that those who accept the reality of anthropogenic global warming see lack of appropriate action as inviting mass extinction of species, including our own, in the not-too-distant future, preceded by incredible hardship, possibly in the lifetimes of people already born, the grandchildren and maybe even the children of people reading this post.  Two bits of censorship prompted my post.

    One of the frequent contributors to the climate change discussions included in a submission the comment that it didn't matter whether people were climate change skeptics or climate change deniers because the effect of what they seemed to support, that is, inaction, was the same.  That comment was censored out.  I became aware of this bit of censorship and decided that it would be helpful if readers understood the difference between skeptics and deniers based on my extensive experience discussing this topic in three different discussion communities.  I tried to share my experience with Engage readers and that, too, was censored out even though what I wrote was about as bland as an explanation could be.  Not too long thereafter the thread was shut down, which, I agree, was a serious mistake. 

    AIChE Engage is a place where members should be able to discuss anything of interest to us as chemical engineers and as whatever else we all are as long as the discussions are meaningful and civil. Even though I have been looking at the climate change issu for years I continue to learn by reading the Engage posts on the subject.  Positive on-line interaction among the members is a good thing and should be supported at all levels.  We can all learn from each other in many areas, including things that are not uniquely specific to our profession.

    This must be the second time I post a comment, as visit the AIChE site I very sporadically (coincidentally, this is again a reply to a posting from Neil.)  I find the aversion to conflict in the moderation of these (supposedly) open discussions quite disturbing.  It is not only OK but very healthy for a community to show a wide diversity of viewpoints on a subject.  The science of climate change is evolving as humanity develops more tools of understanding.  My first stand on the issue is to take a personal responsibility on how my life contributes to the spiraling growth of carbon emissions; for instance, reducing . t a bare minimum my meat consumption (my cardiologist will be proud when I tell him); trying to combine errands to reduce the use of my car (despite my long-standing career with and gratitude to the energy industry); using videoconferencing whenever I can instead of air travel; etc.
    Wait a second! a reader may say... is this a "real chemical engineering" posting? To that I'd say, yes, of course... chemical engineering has informed the way I approach possibilities to make this journey meaningful.  I was fortunate to discover the essence of process engineering and extrapolate the idea of process to everything going on.
    Climate change is the combined effect of the myriad of decisions made by humanity through numerous scientific revolutions. Nos it's time to clean the mess.  I'll be back... and hopefully I find controversy.

    I'm super disappointed that the climate change policy statement thread was shut down.  Over the years I have seen some truly uncivil posts on climate change threads before they got moderated out -- ones that were denigrating personal attacks on the intelligence/age/mental fitness/etc. of another poster -- and not about disagreements over the issue under discussion.  AIChE moderates posts because there is conflict over the issues, and that's not healthy.

    I'm particularly disappointed about the thread being shut down because I want to hear from all of the candidates in this year's election about their stance on climate science.  So far we have only four of the ten:
    Brian Davison, running for Director (supports the science)
    Pete Lodal, running for Director (supports the AIChE policy statement)
    Bob Kiss, running for Director (supports the science)
    Deb Grubbe, running for President-Elect (doesn't personally care about the subject)

    I would still like to hear from the six remaining candidates before the deadline for casting our ballots arrives:
    Gregory Frank of Amgen (running for President-Elect)
    Linda Broadbelt at Northwestern (running for Director)
    Douglas Clark at Berkeley (running for Director)
    Bob Kelly at North Carolina State University (running for Director)
    Ann Lee at Celgene (running for Director)

    Re August 11 post be Kirsten Rosselot:

    I haven't seen many posts that were personal attacks on the writer but there have been some less than gentle comments about some of the postings.  It could be a tough call as to allow or not allow such things if the submissions are reviewed before publication.  It could somtimes be hard to fault the censor in such situations.  What the AIChE censors appear to be doing is something the NSPE censors have admitted doing, that is, to ensure that posts that are utter nonsense are not identified as such because that might embarrass the poster of such nonsense. Sigma Xi takes a different approach.  When nonsense is posted others are allowed to show that it is nonsense.  The result is that a lot less nonsense is posted.  That, to me, is a better way.  The way to avoid getting embarrassed for posting nonsense is to not do it.  People should not be making strong statements about controversial issues without doing at least a little work to determine if their positions make sense.

    I would definitely prefer the approach that Sigma Xi is taking. An adult approach. Labeling an individual’s contribution as “utter nonsense” has to have the intent of soliciting an emotional reply. Especially if said individual was contributing in good faith. The AGW topic is VERY complex. “doing at least a little work to determine if their positions make sense” is not as easy as it may sound. I just did a quick search, sorted by date, on climate change. 2nd hit was something from Dr. Joel Meyers. One could hardly label his observations as “utter nonsense”. Worthy of a critical analyses? Sure. But, what is the non-expert to do with this factoid? Who knows. After following several of these AGW oriented threads I’ve reached the conclusion to observe, only. I do find this very useful. But posting something I find genuinely, scientifically interesting, just to have my basic intelligence questioned is just not worth the effort needed to educate my interlocutor on the error of his/her assessment of my motives or intelligence. I’ve got better uses of my time. Now some folks in these threads have been most understanding and considerate in their responses. I’d put Kirsten at the top of that list.
    Anyway, shutting down these discussions is just a bit bush league.
