I really like the studies that Dancing is better for depression than antidepressants: https://www.independent.co.uk/life-style/dance-best-exercise...

The post I responded to did not mention martial arts.
I'm confused. All of the posts you replied to in this chain mentioned martial arts -- maybe you didn't understand that sparring is part of the practice of martial arts?
I interpret sparring is something boxers do. I never thought of it as a martial art.

Yes, moving as one with your partner is a big part of it, and where much of the pleasure comes from.
Yeah I believe that our brains are extremely sensitive to shared experience, work, art, movement or else (singing in harmony would work too). It might even tap in primitive toddler brain phases.
There's thousands of years of human societal development, and millions of years for mammals. Hard to believe we'd learned nothing about promoting social cohesion during that time.

> The authors' claims about BDNF are supported by a p-value of p = .046, and having main conclusions hinge on p-values of p > .01 usually means the conclusions are rubbish. Your other points I agree with but I actually think the BDNF result has some standing. I'm looking at Fig. 4 and just by an eyeball test there's clear difference in the distributions of the intra-individual BDNF increase. It's not like there's som…
I know nearly nothing about BDNF specifically. Whether it should motivate a follow-up is mostly only something known to the authors, as a p = .046 suggests a chance they may have tested numerous outcome variables and reported only one (e.g,. this could very well be 1/10). The fact that the p-value is almost comically close to p = .05, makes me suspect that this happened. Perhaps, if this goes in line with other BDNF…
> assume there was no p-hacking
Agree that this is definitely an assumption one needs to make, could easily be that BDNF was one variable among many unreported ones, and this case would be consistent with the other outcome variables in the paper so seems plausible.
> this type of result implies that statistical power is tiny,
Yes, definitely, BUT the effect in question is an interaction effect so yeah, power's just going to be small from the nature of the design. I was definitely thinking that you'd be looking at a follow up study of the size of multiple hundreds to confirm something like this. I'm realizing that thinking this is a trivial follow-up is is the difference between someone actually might work on real experiments and someone who just works with the numbers.
Just want to re-emphasize though that the thing which makes me give this result (some) credence (assuming it's not a desk drawer p-hack) is just the distributions of the observation variable for the two treatment groups. Like even if the means of the BDNF increase are equal between the two arms of the trial, and this p-value is a false pos (which as you say, seems very possible), there's still clearly some other differences between the groups. I strongly suspect a quantile regression on the p50 or p75, rather than an ANOVA on the means, would show a 'more significant' effect; heck even just a log-linear model or something seems like it would be an improvement since there's clearly some skew in the 'Dance' population.

#176I do MRI work, and my gut is that none of the claims about dance vs. exercise would replicate. The behavioral data suggests that activity of some type will improve cognitive function (main effects of time). Such beneficial effects of activity on the brain have been shown before, and this is generally accepted. However, the authors' behavioral data doesn't show any difference between the dance vs. exercise groups. Thi…
I lack the in-depth knowledge but correcting p-value thresholds for multiple hypotheses is very basic science. I doubt your criticism is valid given that some basic error like this would never pass peer review.

My random opinion is that dance or dance like activities are a sweet spot between low intensity and high intensity exercise that involves a lot more balance, coordination and fluidity than most physical activities promoted for health overall (they're either too simple or too hard), these traits are (I believe) very important to your brain. Add the social aspect as an important bonus.
Totally anecdotal and probably 99% placebo but I started rollerblading (which also require _a lot_ of balance and coordination) for the first time in my life, like, I take courses in a skatepark and never wore rollerblades before (I’m 33). After some weeks I’m totally perceiving "something" changed in my brain. It’s like doing mental things is somehow easier.
I also happen to microdose since a few months ago but the change I felt coincided exactly about when I felt my fear to fall disappeared, when I "got" the balancing.
That’s totally an anecdote and not science but this feeling of change in my brain was so strong that I perceived it.

#178Not surprised in the least if this is the case.
I have no experience with this app/company but I understand there is some evidence for timing based exercises helping cognition.

Shirts are topologically indistinguishable from crotchless pants; do we have a metric here? https://www.thepsmiths.com/p/review-scaling-people-by-claire... goes into the differences between (in 1984 terms) inner- and outer-party expertise (aka foxes and lions? psychopaths and clueless? morlocks and eloi?).

Below the waterline? (Waistline if less charitable) Ah havent read this article yet but anticipating “insider” as a more distinguishing term than “experts” should cover their edge cases (Which secrets are shameful to share vs merely uh inconvenient, e.g. for waistline, depends on how you draw the party lines, some do it at type ii “zahlungsfaehig” vs “proleten” as nsdap apparently another eg, for waterline) [do you h…
My bad: I got the fox and lion analogy wrong.
(NdBdM apparently said the prince ought to be able to be both fox and lion; like HKH had both Knecht and Designori? What about Tito?
"The lion cannot protect himself from traps, and the fox cannot defend himself from wolves. One must therefore be a fox to recognize traps, and a lion to frighten wolves."

Sorry, I'd been too quick to assume it fit nicely in with our early tripartitions, based on some blogiating that I'm not finding in my verlauf at the moment. So I'd been imagining TCCAG (in Graves' telling), d-d-disguising himself as one of the clueless, in order to survive the machinations of the psychopaths that had killed off every other male in his family: https://en.wikipedia.org/wiki/Julio-Claudian_family_tree#Sim...
Found it: https://en.wikipedia.org/wiki/Circulation_of_elites#Governin... ; it must've been the Burnham connection that set me off on 1984 and then to Rao. Note that here the foxes and lions are distinct people; hence my confusion.
EDIT: Pareto definitely thinks of foxes and lions as distinct, but he must've introduced them somewhat earlier than §2178 (The Mind and Society/The General Form of Society/Force and Class-circulation): https://archive.org/details/ParetoTheMindAndSocietyVol4TheGe...

Not specific to dance here, but just replying to your general thesis: The "just be yourself" advice is so hard, because it's what actually works, but it's also difficult to do when you care about the outcome. And, of course, it has a prerequisite of a whole lot of work to make "yourself" into something worthwhile and interesting. Of course one would like a shortcut that still works if you've not done the prior course…
> The "just be yourself" advice is so hard, because it's what actually work For attractive people or at least those whose attractiveness is not totally niche
Of the dozens of men I work with, two are eligible bachelors. Both are above-average in their physical attractiveness. I promise you, that is not what women are looking for.
