That is not remotely how you use standard deviation.

Yeah pretty suspicious with their frequent flies from Middle Earth to Valinor Island, they should publish their flight schedulesโ€ฆ

When your friends ask you to check the weather forecasts for your nice lil camping trip in the mountains and you forget and then need to shift the blame:

It has warmed my hearth to see we have reached over 200 signatures here :) Thank you to everyone who has put their name down. As this is picking up steam, together with other initiatives, and with some UCAR representatives, we're trying to make sure this reaches the general public, congress & NSF.

19.02.2026 19:05 โ€” ๐Ÿ‘ 16    ๐Ÿ” 9    ๐Ÿ’ฌ 0    ๐Ÿ“Œ 1

We already have over 40 signatures from US researchers and professors supporting NSF-NCAR and telling NSF to maintain control of the NCAR-Wyoming Supercomputer with NCAR! Do sign and share.

Feels a lot like the goose chasing meme. Ok but what are these values that, if represented, would make science better? Because definitely there are scientists that are more or less progressive, more tech-optimist, some are degrowthers, some are liberal, some Marxist, conservative economists existโ€ฆ

14.02.2026 23:22 โ€” ๐Ÿ‘ 11    ๐Ÿ” 0    ๐Ÿ’ฌ 1    ๐Ÿ“Œ 0

The most charitable interpretation would be to say โ€œsince having right-wing values represented in science is important, then it is the fault of right partiesโ€™s utter contempt for science for forsaking that chance at representationโ€. But I still havenโ€™t received an answer about what are these values.

14.02.2026 23:18 โ€” ๐Ÿ‘ 15    ๐Ÿ” 0    ๐Ÿ’ฌ 1    ๐Ÿ“Œ 0

Completely arbitrary and silly (as you said)

What does he mean the axis is truncated it starts at 0?? Where should it end, at 200??

Ok but that confuses the hell out of me and Iโ€™ve been here 8 years, can you imagine how confusing it must be to Hegset?

Right, itโ€™s not like we donโ€™t have a counterfactual right now of both what a right-leaning public space looks like (Twitter) and what a right-leaning science institution looks like (literally every institution in the US government right now??). Is science benefiting from Dr. Oz right-leaning views?

14.02.2026 18:47 โ€” ๐Ÿ‘ 6    ๐Ÿ” 1    ๐Ÿ’ฌ 1    ๐Ÿ“Œ 0

Ok but what are the right-wing -leaning views you think would lead to better science as a whole? Currently, in nutrition, donโ€™t you think indeed the current Health Secretary is a powerful โ€œinstitutionโ€ with a specific leaning? Is nutrition as a science improved by it? How about EPA and climate?

14.02.2026 18:32 โ€” ๐Ÿ‘ 62    ๐Ÿ” 0    ๐Ÿ’ฌ 4    ๐Ÿ“Œ 0

Iโ€™m genuinely not trying to miss your point. Iโ€™m asking you earnestly both what are the specific political views missing that will get us better science (is it different views on immigration? economy? physics?) and how does one get there-or rather whose responsibility is it to ensure that happens?

14.02.2026 17:13 โ€” ๐Ÿ‘ 56    ๐Ÿ” 0    ๐Ÿ’ฌ 2    ๐Ÿ“Œ 0

More broadly: what are the left-leaning views that are predominant in โ€œscience institutionsโ€ and what bias do they produce? Is rigorous science possible in the current extremely right-leaning institutions like EPA, NIH or DOE? How does right-leaning climate science look like?

14.02.2026 17:02 โ€” ๐Ÿ‘ 40    ๐Ÿ” 0    ๐Ÿ’ฌ 2    ๐Ÿ“Œ 0

I got that. So you are objecting to the intertwining-what is unfortunate, to you, is that science is primarily done by people with a specific bias. Iโ€™m saying that itโ€™s hard to see online spaces in which one could right now be right-leaning (whatvr that means: pro-ICE? anti-LBTQ?) and a scientist.

14.02.2026 17:02 โ€” ๐Ÿ‘ 41    ๐Ÿ” 0    ๐Ÿ’ฌ 1    ๐Ÿ“Œ 0

Didnโ€™t you say itโ€™s โ€œunfortunateโ€? Sounds like an objection to it, to me!

14.02.2026 16:34 โ€” ๐Ÿ‘ 58    ๐Ÿ” 0    ๐Ÿ’ฌ 1    ๐Ÿ“Œ 0

You say that โ€œleft-leaning politics and science are intertwined hereโ€. I donโ€™t think climate physics is inherently political - yet there is only one party in the US who is hostile to me both for teaching it and for who I am as a human (a non-heterosexual immigrant). How do I dis-interwine myself?

14.02.2026 15:56 โ€” ๐Ÿ‘ 77    ๐Ÿ” 0    ๐Ÿ’ฌ 1    ๐Ÿ“Œ 0

You id-ed it as โ€œunfortunateโ€, and that the consequences of that have policy implications that are โ€œbadโ€. Hence one might infer that, were they scientists concerned with good policy-making, it would be their duty to stay on that platform to avoid opinionists like you from assuming they are biased?

14.02.2026 15:51 โ€” ๐Ÿ‘ 70    ๐Ÿ” 0    ๐Ÿ’ฌ 1    ๐Ÿ“Œ 0

Seeing that figure and concluding that to be less biased scientists should stay on a platform where they are constantly overwhelmed by abuse, and full of straight up nazis is an incredible form of victim blaming, especially considering the explicit attitudes of the current US government.

Last December, weather and climate scientists sat down with us to tell us why they loved the National Center for Atmospheric Research, and why it benefits us all. Last night, the NSF began dismantling it. Listen to what they have to say, and why it's urgent that we #SaveNCAR wclivestream.com/act

Hey there, for now I was thinking of this as more aimed at US scientists/teachers, considering this is for NSF... but let's see where it goes :)
