Happy Birthday, Internet! 55 years ago, the 1st internet message was sent from @UCLA @UofCalifornia by a team of computer scientists led by Dist. Prof. Leonard Kleinrock @kleinrock @uclaconnection1 @CS_UCLA . Join us for his lecture today to learn more: https://t.co/I9EqiNApUV

Smartphone data reveal how much more Black Americans are policed. The reason why varies by city. Just Accepted new paper by M. Keith Chen @MKeithChen, Katherine L. Christensen @katechristens, Elicia John, Emily Owens @ProfEmilyOwens, Yilin Zhuo https://t.co/GKEB1hkZZa

Yes... I had to censor my work without which my committee wouldn't sign it... But the great thing with Internet is that you can post the original version and even add a disclaimer explaining why it differs from the published version…

1/Today I am thrilled to announce, after years of work, our team @fervoenergy has developed a major advancement in geothermal, proven it at the field scale, and is set to deliver commercial next-gen geothermal decades ahead of schedule. THREAD. https://t.co/5TY16HU19F

Oh, nothing, just a robot programmed to rapidly identify all members of the unwanted species and kill them with lasers.

@morewedge @ProfKMEricson @katy_milkman @HarvardHBS @francescagino @DataColada @OSFramework But I suspect we agree on more than we disagree; we probably both appreciate recent open science changes in our field / hope they accelerate / think there is significant room for improvement.

[Keith Chen @MKeithChen]

@morewedge @ProfKMEricson @katy_milkman @HarvardHBS @francescagino @DataColada @OSFramework I think that's probably right! But I worry if that's our bar.

[Keith Chen @MKeithChen]

@morewedge @ProfKMEricson @katy_milkman @HarvardHBS @francescagino @DataColada @OSFramework Maybe this is too low-bandwidth of a channel to really understand this though, and lots is currently happening. Would love to hear your thoughts next time we run into each other.

[Keith Chen @MKeithChen]

@morewedge @ProfKMEricson @katy_milkman @HarvardHBS @francescagino @DataColada @OSFramework I'd like to understand where we disagree Carey, I take it that you don't think low replication rates and cases of fraud are real evidence? Maybe we disagree on what the claim is? I think we have evidence of problems with the reliability of experimental behavioral science

[Keith Chen @MKeithChen]

@morewedge @ProfKMEricson @katy_milkman @HarvardHBS @francescagino @DataColada @OSFramework and yes, i don’t think behavioral science is unique in this, (but we do seem worse than most?)

[Keith Chen @MKeithChen]

@morewedge @ProfKMEricson @katy_milkman @HarvardHBS @francescagino @DataColada @OSFramework i agree we shouldn’t rely on intuitions, though we do have data on low levels of replication, and that is as telling as cases of fraud, maybe more so.

[Keith Chen @MKeithChen]

@ProfKMEricson @morewedge @katy_milkman @HarvardHBS @francescagino @DataColada @OSFramework As examples, only one author collecting and touching the data seems common, and failures of replication seem to have no negative repercussions for the original authors. Both seem to suggest the field doesn't prioritize / incentivize reliable science.

[Keith Chen @MKeithChen]

@ProfKMEricson @morewedge @katy_milkman @HarvardHBS @francescagino @DataColada @OSFramework I think this take is wrong @morewedge, I don't think behavioral science appears to have taken failures of replication and the worse cases of fraud seriously enough; the field doesn't seem to be to be self-correcting.

Why Remote Work Could Lead to Less Innovation

A new study by Professors @MKeithChen (@uclaanderson), David Atkin & Anton Popov (@MITSloan) suggests that when employees from one company run into employees from another company, creative sparks fly.

@ColebRob @KricheliKatz @regev_tali I agree we don't know how much of the increased spread is between vs within subjects, but that distinction doesn't affect the main prediction: weak-FTR will decrease the value of future rewards either way.

[Keith Chen @MKeithChen]

@ColebRob @KricheliKatz @regev_tali Between subjects, FTR appears to have temporal effects: weak-FTR treatments decrease temporal precision. That's the temporal-precision effect that I think the experiments support.

[Keith Chen @MKeithChen]

@ColebRob @KricheliKatz @regev_tali We should hop on a zoom and talk at higher bandwidth, but in these experiments, the amount of future rewards is not uncertain; so there is no role for reward uncertainty
