This work was inspired by an awesome similar study by @johnflournoy.science 2024 (pubmed.ncbi.nlm.nih.gov/38141745/), obviously the midnight scan club @gordonneuro.bsky.social 2017 (pmc.ncbi.nlm.nih.gov/articles/PMC...) and many other amazing recent studies in precision imaging

Whether this multilab project actually takes place depends on the availability of funds, but I hope the funding will materialize! I cover this classic study in my cog psych class, but, as the graph shows, the effect is rather small. I'd be interested in finding out what comes out of it.

@rolfzwaan.bsky.social is organizing a multilab replication of Loftus & Palmer's (1974) classic study: People's memory of two cars' speed was influenced by the verb used in Q ("How fast were the cars moving when they ____"). This is exciting, & if you want to take part in it, check out Rolf's post.

A graph summarizing the results of the Loftus & Palmer (1974) study, indicating that the estimated speed of the cars varies as a function of the verbs used in the questioning (e.g., contacted, hit, bumped, collided, smashed).

The graph is from this site: https://www.earlyyears.tv/loftus-and-palmer-1974-car-crash-experiment/

Here's a replication of an informal Big 5 result I posted yesterday (the original post is pinned on my profile page). Glad to see that @aurelienallard.bsky.social found the same result. I'd love to see more attempts like this on Big 5 or other constructs. Thanks, Aurélien, for doing this analysis!

Aurélien Allard @aurelienallard.bsky.social · 29d

So cool! For what it's worth, I've just tried to replicate the result for the 50-items IPIP from open psychometrics (openpsychometrics.org/_rawdata/). There's also 0 participant falling into each average category for this dataset. If constructs were orthogonal this should have been 6 (out of 20,000)

I'd be happy to ask the grad student who did this analysis as a part of a little class project, but, in the meantime, here's a Big 5 replication attempt by @aurelienallard.bsky.social. I'd love to see how our and his results fare in other datasets.

Here's some replication by @aurelienallard.bsky.social using a different dataset based on 50 items in case you're interested. I'd love to see more replications w/ Big 5 & other psychological constructs (e.g., intelligence).

At least some (possibly all) of the 10 body measurements are likely to be correlated (even substantially), so I tend to think that the math based on total independence might not quite capture what happened in the Daniels pilot study.

Cool thread. Excellent reminder that bodies and personalities (and faces fwiw) are multidimensional, and that averages are poor lenses with which to examine them. Further, relationships within/between dimensions may be complex - jagged, yes, but also networked & dynamic

ANSWER: 0 (yes, ZERO!)

This is a result of an analysis done by a student in my grad seminar, using a large dataset (N=307,313).

What this result might mean: Nobody's personality is truly "average," and people's personality profiles (at least Big 5) might be more "jagged" than we think.

Imagine you have Big 5 personality scores from over 300,000 people. You designate the scores in the "mean +/- 0.25 SDs" range for each trait (~20%) as the average range.

QUESTION: How many people in this >300K sample do you think fall in the average range for ALL 5 TRAITS?

What's your answer?

I'm happy to now be able to share a talk I gave at TEDx New England last Fall!

The talk is about our lab's work on what makes decisions costly, and how to make them less so.

I discuss lessons for all kinds of decisions, including getting people to vote.

Well, the answer turned out to be ZERO! (A follow-up thread pinned to my profile page provides a bit of an explanation of what we did.)

The answer turned out to be ZERO in one informal analysis (see a follow-up thread pinned to my profile page for more info).

The Seahawks didn't do well, either, today, especially at the very end. Sigh...
