Today it’s official:
my ERC CoG proposal on the full spectrum of opioid effects was funded 💃🤩💃

(Short description found here: affectivebrains.com/portfolio/spectro/)

Thrilled to be celebrating this & other wins of 2024 with this wonderful group of colleagues
⬆️avoidance learning / negative reinforcement in opioid-treated patients (26 chronic pain, 24 OUD)

Cool project

🤔
Are opioids the common factor, or another vulnerability?

Chronic pain, depression, anxiety, fatigue, addiction ... All comorbid & w/ same predictors

Increased Avoidance Learning in Chronic Opioid Users
This case-control study determines whether opioid addiction is characterized by increased avoidance learning and whether this is also observed in individuals with chronic nonaddicted opioid use.

Another key aspect of stopping the new information tech (radio) from ruining democracy 100 years ago was gov’t regulation.

Amongst many other regulatory tools, we regulated radio ownership. We also created public media to serve the public interest. The BBC came from the same motivation.

Citation impact and actual impact are not the same thing. What is the prototypical paper from the social-behavioral sciences that had both a huge citation impact and a huge actual (by your definition) impact?

Great thread
There still seems to be a lot of confusion about significance testing in psych. No, p-values *don’t* become useless at large N. This flawed point also used to be framed as "too much power". But power isn't the problem – it's 1) unbalanced error rates and 2) the (lack of a) SESOI. 1/ >
But here's, the thing, p values and significance become useless at such large sample sizes. When you're dividing the coefficient by the SE and the sample size is in the tens of thousands, EVERYTHING IS SIGNIFICANT. All you're testing is whether the coefficient is different than zero.

Hi early career researchers

I know job interviews can feel a bit like exams

But having done six in the last week, let me tell you

Chances are you’ve blown the minds of the interviewing panel 🤩🤩🤩

Seriously word?
I have long complained about the absence of ‘interoception’ from Microsoft Word’s internal dictionary, but today I would also -shockingly- like to highlight the absence of ‘orgasm’. New paper (with many unrecognized words) coming soon.

Been working a lot on own & colleagues’ grants recently

Many great proposals define the problem so narrowly that it leads directly to the solution the project offers

When I was an undergrad, I saw a talk by Oliver Sacks about music. During the Q&A, someone asked Sacks if he thought science would reveal the deepest mysteries of art. Sacks (a rare humanist among scientists) said that he doubted it, at which Eric Kandel (the host) leaped up and grabbed the mic.

Our systematic review and meta-analysis is now published in Neurobiology of Stress 🍾

Main takeaway: glucose increases cortisol stress reactivity (robust, small effect), but effects of progesterone and estradiol are weak and rather inconsistent. Read more about it here 👇🏻
📣 Excited to share that my first paper is now published!

Great advice on universities at risk of accepting the Compact: "Really all you need to do is get your campus to hand this issue over to a very, very slow committee!"
We now enter the most dangerous phase, but also the one with the greatest opportunity. The U.S. has thousands of colleges, some run by red state governments, so it's too much to hope that NONE sign up for this federal takeover.

But it matters WHO signs up. The administration is taking a risk.
After getting zero firm commitments to this point from the first nine invitees, the Trump administration is extending its proposed compact to all colleges. Expect some red-state publics to say yes.

Point of view, Norwegian time optimist

Optimal arrival for 6 pm dinner: 6.10
Earliest polite: 6
Latest polite:6.20? With message, 6.35 🤷‍♀️
If you are invited to someone’s house for dinner (say, at 6:00), what’s the earliest you might arrive and the latest and still be considered polite?

(Bonus q: what’s the *optimally* polite time?)

I’m curious how this varies culturally/regionally/generationally.

Interesting how companies and the financial world is racing to spend mindboggling amounts of money to build the infrastructure to train computers. But we are leaving the infrastructure to train and educate humans crumbling. The question is who will train who?

The Nobel Prizes, 5 of 6 having so far gone to US based scientists, are a reminder of why we must stand up for science against this horrid administration. Here are some great Scientist Activists to follow.
