I don't think I have one. Somewhere in my lab I have an old videotape from Dick Neisser. If I can find it, I'll have it digitized professionally. I don't think the Neisser & Becklen (1975) videos were, though. Maybe @irahyman.bsky.social has that one? Happy to post other variants to my channel.

Neisser 1979
YouTube video by Daniel Simons Neisser 1979

The original Neisser selective looking video is now posted. The description has lots of details: www.youtube.com/watch?v=7g7a...

@irahyman.bsky.social - if you have some of the other variants, I'd can post them. too. I don't have them handy right now.

I used to have it up there. Not sure why I don't any more. For a while, I was handling requests for it for Dick's children, but I haven't needed to do that for a while. I'd be happy to repost it if you think that would be best for visibility.

I'm teaching my grad version of the course again this fall. I haven't started working on the syllabus yet, though. It's my first time teaching it in the LLM era, so that'll be a new challenge. I'd love to see what you're putting together!

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.

It used to be a decent journal. Years ago I submitted what I felt was good work and it underwent rigorous review. Haven't gone there for years due to the increasingly iffy approach to review.

The Troubling Legacy of James Coyne Psychology's infamous bully

"Coyne’s blogs were verbose and erratic, often veering into personal attacks. He freely fabricated conspiracies and leveled baseless accusations that obscured whatever legitimate critiques he might have had."

The Hare-Brained Generation: Teen mental health crisis or lacklustre record keeping? In The Anxious Generation, Jon Haidt argues that social media is driving a mental health crisis among teens. It's a compelling thesis, widely discussed in the media, mostly accepted by my students and...

New post on The 100% CI: I read @jonathanhaidt.bsky.social's and @lucyfoulkes.bsky.social's book on the alleged teen mental health crisis and social media's role in it. Then, I tried to make up my own mind, with limited success.

It was @cfchabris.bsky.social's blog post by about Dobelli's plagiarism of The Invisible Gorilla in The Art of Thinking (he also cribbed passages from Taleb). Although Chris's blog is down, Dobelli's website lists his "corrections" (www.dobelli.com/book-correct...) @axc.bsky.social

Really enjoying @profsimons.bsky.social & @cfchabris.bsky.social β€˜Nobody’s Fool’. Yet more content for my β€˜Thinking Like a Psychologist’ module next year. This stuff seems to me to be vital for the future of the discipline

Just 1, actually. Steve most is the only one in the pack who was IN the video.

Looks like it's just those two on Bluesky so far. I have contact info for 4 of the remaining 5, but none are on Bluesky. I'll keep checking periodically in case they show up.

I know two six of the players are here. Not sure about the remaining four or the person in the gorilla suit. Chris and I weren’t actually in the video. I’ll do some digging to see if I can convince any others.

Not sure they’re all on Bluesky yet, but at least a couple of them are :-). Gotta convince the rest of them to make it happen

One thing I wish I saw more from communicators especially on health & medicine:

Let's be more vocal about the positives of interventions that work.

Yes, it's important to push back on misinformation, poor research practices & clarify side effects. But let's not forget how important this all is.

🧡Next week, you will see people using something called Benford's Law to try to prove election fraud.
⛔️These people are wrong⛔️
I am a scientist who has published on Benford's Law. Let me tell you what it is and why what they are doing is mathematically incorrect. 1/

Jonathan Haidt Started a Social-Media War. Did He Win? When a study challenged his bestselling book’s thesis β€” that social media harms kids β€” the New York University psychologist fired back. That was just the beginning.

NEW: I wrote about a study that challenged β€œThe Anxious Generation,” Jonathan Haidt going to war over it, and the chaos that ensued. Here’s how a fight over science and social media got messy, fast. www.chronicle.com/article/jona...

The github readme has a link to a website that implements their version of statcheck. I don't know if that's the latest version. I didn't play with the actual R package, so maybe it's more robust.

I tried the online version with the pdf knit from a markdown file and it didn’t find any of the F tests that were in APA format. Not sure why.

Plotted version of png converted to data with regression fit line. It appears there's a positive association between steps and sleep. But the simulated data points spell out "OH NO!"

Here's a fun way to encourage students to always look at their data. A few years ago, I wrote a script that converts a black and white png to data and plots it.
