Cool idea. I imagine there is also an intrapersonal version of this (me vs future me). When trying to establish a new habit, it might be important to have clear rules with no exceptions.

Very useful. Are there papers you can point to on this (especially on 5 vs 7 point Likert scales)? For sliders, is the idea that excessive granularity = less reliability?

We examine that in the paper. Maybe you should read it first.

Another policy that would address your concerns, and would be far more efficient, would be lotteries (random assignment of grant awards)

Don’t disagree, but it’s worth considering how much wasted time and labor (for applicants, reviewers, and tax payers) we are paying and how much marginal meritocracy we are getting in return. Pretty sure the current system is not a good trade-off.

David Tannenbaum @davetannenbaum.bsky.social · 20/10/2025
But I admit, assuming ideas have zero causal force is a strong assumption.

David Tannenbaum @davetannenbaum.bsky.social · 20/10/2025
The question is whether having applicants write about their ideas, and reviewers evaluate them, actually makes things any more meritocratic than just posting a CV. If it doesn’t, then just posting a CV is still a win because doing so stops wasting everyone’s time.

David Tannenbaum @davetannenbaum.bsky.social · 20/10/2025
Open question whether the just-my-CV approach generates more bias than the current regime for grants. Not clear to me it would. Also would be an easy fix to have applicants remove institutional information from a CV.

I have the same intuition. Also think there is going to be more agreement/consensus across people on what is bad than agreement on what is good. Assume it arises because of negativity dominance (our minds show greater differentiation to shades of bad than to shades of good)

Got it, thanks Vlad. Looking forward to the morality measurement paper, will keep an eye out for it!

Congrats on the paper. Would repeated measures within-groups or within-individuals (such as ipsatized scores) get around the issue?

David Tannenbaum @davetannenbaum.bsky.social · 22/05/2025
But I agree with your broader point, that we should care what your theory predicts not what you predict.

David Tannenbaum @davetannenbaum.bsky.social · 22/05/2025
As a reviewer/editor, don't you think it's makes more sense to ask for some kind of additional corroboration (such as a replication) in (1) than in (2)? The only difference is (1) is exploratory and (2) is confirmatory. Prereg helps us distinguish exploratory vs confirmatory.

David Tannenbaum @davetannenbaum.bsky.social · 22/05/2025
Consider two scenarios: (1) "We ran a study, did a bunch of analyses, stumbled across this interesting 3-way intx seems consistent with theory X" (2) "We were interested in testing a specific 3-way intx predicted by theory X, and designed a study to test it." Assume the same sample size in both.

David Tannenbaum @davetannenbaum.bsky.social · 22/05/2025
A big part of preregistration is to make papers more evaluable for editors and reviewers (e.g., your 'predicted' 3-way interaction becomes a lot more credible if you stated your predictions and analysis plan in advance). Author's professed reason for prereg is somewhat besides the point.

Also pretty cowardly that they won’t put their name on their work. If you don’t think your study was unethical, then fully own up to it.

To your point, UT Dallas business school created a journal list to rank different b-schools by research productivity. It just so happens that UT Dallas ranks #2 on that list.

In Figure 5, all of the t_-1 & t_0 correlations are identical to the corresponding t_0 & t_+1 correlation. That has to be an error, no?

Can someone make a starter pack of all these starter packs?
050
David Tannenbaum @davetannenbaum.bsky.social · 28/09/2024
Correct. Or at the very least, you’d have to do something else, such as use GLS instead of OLS (RE model instead of FE) or exclude the FE terms and recognize that they are confounded with your treatment

David Tannenbaum @davetannenbaum.bsky.social · 27/09/2024
I would also add "normally fine so long as your FEs are not perfectly collinear with your predictor of interest". Otherwise the FEs that are dropped (due to collinearity) are going to get absorbed by your predictor and screw everything up.

Not sure I follow the last part… how do open science principles come “at the expense” of creativity and exploration?

A command-line interface for designing/writing a study. Would love to be able to edit text scripts, rather than a janky graphical interface with a slow back-end that is constantly stalling out.

Sure. But most studies are time stamped, and you’ve now has created a paper trail with the pre-reg.

We recently wrote a response to a paper that had the same regression error issue that Kim is pointing out in the Ciacci paper. The authors of that paper used Stata, and we replicated the issue in both Stata and R. davetannenbaum.github.io/documents/Ta...

From my experience Stata and R do the exact same thing here — if you have perfectly collinear variables, the variable entered first on the the right hand side is preserved and subsequent variables are dropped.

David Tannenbaum @davetannenbaum.bsky.social · 28/03/2024
Stata gives an explicit warnings that it is dropping due to collinearity. No different from R in this respect.
