This is a masterclass in deceptive statistics, using one of the most common deceptive techniques: relative change across unequal groups. Note the legend on the top left, and that teenage girls in 2020 (post "sudden change") still have the *lowest rate* of all groups. .
This is what I've been trying to say: when you merge everyone and everything, you often find nothing. But when you zoom in on teen girls (especially in early puberty) you usually find a sudden change between 2010 and 2015.

Dear Editors,. If you find a reviewer leaving comments like this, send them a private email telling them that if they cannot be professional in reviews, they are not welcome to submit manuscripts in the future.
I am truly hurt by a comment received from a reviewer today, and it even makes me wonder if I should continue to seek PhD programs.

@ericneumannpsyc Write as if someone can read only the first sentence of every paragraph and fully comprehend every point you make. This advice radically changed how I draft papers: I outline an entire paper by writing each paragraph's 1st sentence, then 2-3 bullets that'll support the sentence.

I'm loathed to defend economists, but this (very real) pay gap is b/c they've disabused themselves of two toxic ideas other social sciences still hold to: . (1) Everyone entering a PhD should strive for academics jobs.(2) Non-academic jobs are inferior to academic ones. 1/2.
We are all doing the same job. We teach the same number of classes. I don't think my labor is worth $20,000 LESS than that of my econ colleagues. More money please.

@eduleadership Ah, no dude. I'm saying that if you take the most absolutist version of Haidt's argument, you're looking at only 163 deaths per year, less than half the death count of pool drownings in the US. And Haidt has no evidence that very small increase is caused by social media/phones.

My paper with the amazing @profcikara in @NatureHumBehav is now published online! We find that people significantly overestimate outgroup negativity toward the collective competitive behavior of their ingroup. Preprint in the followup tweet.

If Haidt's book were titled "phones/social media are bad sometimes" then this would be good evidence, but it's not. He's making grand claims about "rewiring" of kids brains, then large causal claims about societal shifts, then calling for significant government intervention. .
A review in Nature, by @candice_odgers, asserts that I have mistaken correlation for causation and that βthere is no evidence that using these platforms is rewiring childrenβs brains or driving an epidemic of mental illness.β Both of these assertions are untrue.

A reactionary centrist has to propose abstract hypotheticals about what happens in college classrooms in order to reinforce moral panics they make a living complaining about b/c they cannot demonstrate the imaged issue actually exists at scale. At what point do you block them?.
A prof uses their position in a course to advance social justice as they see it. They're engaged in: 1) fulfilling a moral obligation; 2) a righteous choice 3) a defensible choice 4) a suspect choice 5) an unethical choice 6) an abuse of power. What does your answer turn on?.

Fellow #psychology people, I need your help . I know "Maslow's Hierarchy of Needs" isn't validated, and is a "zombie theories" that persists outside of psychology . But what is a validated alternative? Names, literatures, and any suggestions for directions to look are welcomed!.

Takeaway #4: The market is a lottery. When you've been on the market for 5+ years, you realize this, and honestly it's hard for it not to breed resentment. You're gonna see 27 year olds with zero pubs get Ivy TT jobs, while you're ~12 pubs get you nothing. You're gonna see. .

Takeaway #3: The market is an awful experience. It's difficult to describe the mental weight of the precarity and uncertainty the market thrusts you into. Even under "ideal" circumstances it's 6 month between submission and job acceptance. .

Can someone explain why "a calling" necessitates having no power within an institution? The idea that being intrinsically motivated means you have to accept domination is bullsh*t, motivated (per his admission) by the desire to extract value from underlings' work. Total nonsense.
Graduate students are primarily students and trainees, not ordinary workers. Academia is a calling. I suspect unionization will tip the balance so faculty prefer, at the margin, to hire post-docs to do research in their labs rather than students.

Takeaway #1: The market is a massive time sink. In the Fall just applying for the jobs can easily take 5-10% of your time over 2-4 months. Preparing materials can easily be weeks worth of work, and fly outs easily consume a whole week by themselves.

Psychologist here. mandates are very convincing, not merely in a coercive but in a moral sense. People update their normative beliefs based on what is required of them. Not mandating something conveys to people that the behavior isn't that important.
Mandates are stupid. As are vax passports. Ask any psychologist, game theorist, or person who has run a business. We are more collectively compliant when we are CONVINCED and not shamed.

My personal fav is when I learned that "IV" and "Covariate" are the same thing statistically, it's really just a statement of what one cares about.
Statistics terminology is truly unhinged. Different names for the same terms across fields. The same names for different things across fields. Common language terms applied in highly specialized ways. Two similar terms used to mean entirely opposite concepts.

#psych #openscience #stats folks:. Can you recommend a good paper on why (1) MANOVAs are bad, and (2) what should replace them? . And yes, this is for a review I'm doing. I want to give the authors concrete suggestions for alternative to MANOVAs.

Hard no for me. The purpose of IRBs is to protect the rights of participants. Asking them to also police research quality (something they rarely have training in) cannot go well. Unless the IRB is going to offer funds to increase sample sizes, it should stick to its job.
Question:.Imagine youβre on a university IRB/ethics panel and notice that you often receive applications for underpowered studies. At what point does sample size become something the IRB should consider? Where is the line between bad design that is vs. isnβt an ethics issue?.

Takeaway #2: The market is a multi-year time sink. I don't think I'm much of an outlier having done 4 years of post-doc-ing. The two post-docs who previously worked in my lab at Princeton had similarly 4+ of post-PhD experience before getting TT jobs.

I wanna give a shoutout to @annemscheel. A week ago she wrote an article expressing worry about the speed at which COVID related psych studies were being run, and that we might be sacrificing our scientific standards in pursuit of "rapid" (and putatively impactful) research.

Can anyone point me to recent papers which have (1) a small sample size, but (2) have many repeated-measures/trials, and are therefore still highly powered to detect within-person effects? . #psych #OpenScience.

@TheMorgenroth Playing tabletop RPGs (e.g. D&D) gave me a better intuitive understanding of statistics than any course I ever took. Rolling lots of critical-failures on a d20 is perhaps the best way to truly understand what p < 0.05 means.

For all the ECRs (and all academics). One thing I learned while organizing this workshop, and especially in choosing who to invite, is that you *NEED to have a baseline online presence*. You have *no idea* how many opportunities you're missing b/c folks cannot find you online.
This past weekend we hosted "The Euro-American Interdisciplinary Workshop on Disinformation" at @ClemsonUniv. Cosponsored by the @WattCenter and @NATO Public Diplomacy, we brought together an amazing group of scholars to talk about their research. Let me tell you about it!.
