CDS has been known for a while (although under the rather stigmatising term Sluggish Cognitive Tempo). It derives from research on ADHD and the new study lends further evidence for both syndromes being distinct from another.

Traits they predict: slipped in there at the end of the list for "Neurological and mental health" is "intelligence". Just so you know. To be clear: PGD for nasty and often rare monogenic conditions can be really valuable and important. For highly polygenic traits, the efficacy is EXTREMELY unclear.

I’d like to take this one step further: poor communication & hype often already start in sci papers. “Because this study was only observational, no causal conclusions can be drawn” followed by a discussion of policy implications and theorizing based on a causal conclusion.

BlueSky must have the juice if we’re getting weird drug misinformation now! Ketamine does not “share the same brain pathways as opioids” nor does it “interact with the opioid system,” and nobody who knows what they’re talking about talks like that. In case “according to the DEA” didn’t give it away…

Elon Musk's drug of choice is ketamine. While Musk claims it is prescribed by a physician, ketamine is widely known for its illicit use as a recreational drug.

Es ist kurz vor den Feiertagen und Georg ist wohl heute mit dem Gedanken aufgewacht "time to choose violence". Mein Eindruck ist eher, dass die Psychologie verkrampft empirisch sein will und sich weigert, andere Aspekte vernünftig zu integrieren. Denke da an Freunde, die qualitativ arbeiten.

A note for the festive period. While "An Irish Goodbye" commonly means to leave with no notice, a true Irish Goodbye requires an announcement that you're leaving, an "I'm actually leaving now" round of goodbyes, and 40 minutes at the front door nursing your keys. Know your goodbyes. Choose wisely.
