Anyone still on here? If so, and you do surveys with open text box responses, you might be interested in a new analysis guide we've just had published with @SJDMOfficial @SJDM_Tweets cambridge.org/core/journals/…

New paper with @cogsci_soc looking at how people update propensities under uncertainty - we find many update 'categorically' which amounts to a novel form of confirmation bias. Thanks to co-authors @david_lagnado @profnfenton @AdlerNine and @SamuelGBJohnson for great reviewing :)

@smfleming Hi Steve, my 1st daughter is 2 months now - I took 1 month and spread a couple of weeks annual leave over another month. Salaries a major decision factor in me not taking more - I earn ~10k more as a lecturer despite partner equally qualified in equivalent seniority in the NHS

@maddi_pow @themichjam @GiselaGovaart You're welcome, thanks for the paper - I might be in touch to ask you guys to speak at UCL some time :) Also, not sure what the status is of the full publication, but if you're struggling to find reviewers to recommend ... 👋

@TheComplexBrain @themichjam @GiselaGovaart Thank you for sharing!

Just found an awesome preprint by @themichjam @maddi_pow @GiselaGovaart 'Reflexivity in #quantitative research: a rationale and beginner’s guide' - Yes, yes, yes! It's definitely making it's way into my '#qualitative and #mixedmethods' module next term! psyarxiv.com/xvrhm

@david_lagnado @alice_liefgreen @SamuelGBJohnson @ProfRuthMorgan Congratulations Alice, well done on a great PhD!

Massive congrats to @alice_liefgreen who passed her phd with flying colours today - she’s produced an amazing body of research and I’m privileged to be involved - thanks also to 2 great examiners @SamuelGBJohnson and David Shanks and to @ProfRuthMorgan 🥳🥳

Stop funding research (the way you do) Because it is wasteful, unethical and unscientific A thread (1/16)

@StevenMBelknap @NinaStrohminger What if it's a bit of a mix? I think the theory predicts this, but someone else might not ...

@NinaStrohminger If it’s purely personal, it’s not an hypothesis.

@NinaStrohminger I would love to see a history of the relationship between the idea of the ideal theory-derived hypothesis, where it being a priori shouldn't really matter, and the more personal version we actually see, where it does to prevent cheating (lol) - anyone have a good link?

@Jm32745851 @NinaStrohminger That's just what the textbook says - the softer the science, the more subjective and personal (and useless) the 'hypothesis' tends to become

@NinaStrohminger The Hypotheses we test aren't gut feelings. They're predictions derived from models

@DoobieDuh 😁 Yes this could be a subtle contributor to publication bias along with all the other ways the whole process is just a total PITA

@TheComplexBrain This somehow reminds me of the stats lecture 8 😂

Something that would be amazing: a journal rejects your manuscript after receiving reviews because it doesn't fit their remit. They send your manuscript complete with the reviews to one of their parent company's other journals which they think would be a more appropriate fit.

@nicholaraihani Yes I've noticed this with a preprint put on researchgate

I've asked this before but does anyone else find that once their preprint is on PsyArXiv, then search engines never find the published journal version? Does withdrawing the preprint help with this? It is a disincentive to post a preprint tbh.

@chrisdc77 @annemscheel I agree our hypotheses are often underspecified but see this as the reality and reason to give up that approach and accept that most of our work is exploratory, not push harder on forcing everyone to specify precise hypotheses when they don't really have one

Worth reading this rebuke of psychology by @annemscheel in which she channels Bohr & Meehl in a way that will offend lovers of “nuance” Expect plenty of snark, pedantry & passive aggression in response. And when that fades, as always, expect progress 🔥 psyarxiv.com/8w2sd/
