I've got one, but one of the response options (three grammatical genders) was always hypothesised to become more preferred due to the intervention. So I code the responses as expected v not expected for the analysis.

Beats me. Could just be a knee-jerk reaction to consider any definition whatsoever narrow.

I've heard some people say that this precise definition is a very narrow one - whereas I can't think of a broader one.

Cheers, but this doesn't really fit snugly into any of the categories. :)

PsyArxiv doesn't accept new submission for the time being, so if anyone could suggest a preprint server that doesn't require me to jump through a bunch of hoops, please let me know. :)

Thanks for the suggestion, I'm looking into it.

Yeah, and with glm in particular, things can get pretty weird when adding or removing predictors in this way.

17.12.2025 10:52 πŸ‘ 2 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

I agree. I'm doing the analysis the authors think they did and find different results than they did. I don't think these analyses are *good*.

17.12.2025 10:48 πŸ‘ 1 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

Yeah. So now I'm wondering if I ought to send this to the outlets that covered the original study.

They make me frown, too! The context here is that the authors wanted to show that their results are 'robust' even when controlling for per-capita GDP etc. In actual fact, they controlled for GDP (not per-capita) instead, so I merely redid the analysis they wanted to do but didn't.

Positive trend between monolingualism and accelerated ageing.

Negative trend between per capita GDP and accelerated ageing.

Negative trend between per capita GDP and accelerated ageing.

A recent study purports to have found that multilingualism protects against accelerated ageing. I've taken a closer look at it, and it doesn't look good.

My hunch: it's not the # of those samples that are effective, but what effectively the sample size is. (Large nr. of people vs. Nr. of large people.)
