Glad you liked it @ajgillett.bsky.social And a big thank you to AIMOS for the invitation to talk about my favourite topic

Great talk by @wchiggins.bsky.social "Rethinking measurement validity". Wendy introduces an interesting distinction between 'validity potential' and 'realised validity' to help untangle some problems in measurement practices in psychology: www.youtube.com/watch?v=ni4N...

1/ "Silicon samples" are becoming more and more common in research and polling. One problem: depending on the analytic decisions made, you can basically get these samples to show any effect you want. The updated version of this preprint is now online! THREAD🧵 arxiv.org/abs/2509.13397

Survey research is often interpreted as showing that belief in conspiracy theories can be surprisingly widespread, including belief in conspiracy theories that would be astonishing if true. For example, in The Atlantic we learn that “12 million Americans believe lizard people run our country”

Let’s stop talking about “valid measures.” No measurement procedure will *always* measure what it is supposed to measure. Instead: Consider Validity Potential when selecting a measure. Check for Realised Validity when interpreting its output.

We also argue measurement requires a causal relationship from target attributes to measurement outcomes, making it a causal claim. Upshot 1 even correlations between measured variables rely on causal inference. Upshot 2 since good causal inference is hard, establishing realised validity is hard.

Validity Potential = how likely is it that this measurement procedure will measure what I want it to measure? Realised Validity = does the specific output I collected from this measurement procedure measure what I am interpreting it as measuring?

A lot of psych is already conducted with online convenience samples & ppl are probably excited about silicon samples bc it would allow them to crank out more studies for even less 💸 How about we reconsider the idea that sciencey science involves collecting own data. www.science.org/content/arti...

My editorial on how journals can earn trust. We often use journal names as proxies for quality. This is bad bc it’s not valid. But it could be. Editors could make journal name a valid signal. And we could place value on journals that show us how they do that. journals.sagepub.com/doi/full/10....

Have you every found yourself wondering whether the most widely used measures of social cognitive ability measure what they are supposed to measure?
