         | I played ping pong on VR the other day, and it was amazing!
         | I've played a bunch of ping pong in real life, and the physics

         | exactly life-like. It was truly a mind-blowing experience. It

         | iceberg in terms of what kinds of things we could do with VR.
         | Up until now, the games we could play had the limit of only
         | taking a few key presses and mouse motion as input. Suddenly
         | we're now afforded the entire realm of physical motion. Not to

         | endless.

               | There are many kinds of dance and styles. I guess the

               | 
               | Even for seasoned dancers there is a lot to offer in all
               | of those. In partner dance you have to watch and adapt to
               | your partner all the time (no matter the skill level). In
               | choreography you of course have to learn new programs and
               | execute them well (displaying the desired artistic
               | expression), in improvisation you have to come up with
               | things on the fly.
               | 
               | Unless you get stuck in an old routine (same old

               | almost endless variation and learning of new tricks and

       | staying within a group movement which requires both reading where
       | "the group" is and giving space to individual differences.
       | 
       | Obviously the focus here is on exercise but I would be curious if
       | a less physically demanding but similarly grouped activity would
       | have similar effects on brain function. I suspect that linking

       | Two anecdotes from 10+ years argentinian tango dancer.
       | 
       | 1. I dance leading part, and I found myself more self-confident
       | in my engineering leader and manager work. Giving team a
       | direction became more organic and easy. I actually had to start
       | restraining myself to motivate people's creativity. It is
       | actually kind of dance move too: stand still and give my follower
       | firm support to decorate her part with small movements with
       | music.
       | 
       | 2. One of my fellow partners is playing intellectual games (local
       | franchise of "Jeopardy!" and several others). She says her
       | performance degrades with her progress in tango, because the
       | follower's part in tango is to listen and not to step by her own,
       | but only when and where the leader leads.
       | 
       | I also believe in neuroplasticity and overall positive impact of
       | creating and cohesion of neural links.

           | you going with the flow. And getting that trance-like feeling

       | Sorry to be a wet blanket, but:
       | 
       | When looking at studies, there are two types of validity to pay
       | attention to, "external" and "internal." Internal is the sort
       | that says: does this study actually test what it claims to? If a
       | study looks in a black box, sees there's no elephant inside, and
       | says "there's no elephant in there! Huzzah, we've proven it's a
       | tiger!", that's an internally invalid study. External validity is
       | about applicability: if I give a dose of abx to a bunch of people
       | with advanced AIDS to treat an infection, and find it doesn't
       | work, it doesn't mean "this abx doesn't work." It means "this abx
       | doesn't work /in this population/. Don't extrapolate it to an
       | immune-competent population."
       | 
       | 1. The study begins with what they describe in their registration
       | documents as "healthy elderly." That's a bit kind: "Sixty-two
       | normal volunteers, who responded to a local advertisement, were
       | screened. Subjects with any neurological condition, metallic
       | implants, claustrophobia, tinnitus, BMI <=30, high blood pressure
       | (systolic<=140 mmHg), diabetes mellitus, intensive physical
       | engagement (more than 1 hour/week) and abnormal performance in a
       | cognitive screening test (MMSE < 27)[32] and a test devoted to
       | depressive symptoms (BDI-II > 13) [33] were excluded." In short,
       | they started with an _anomalously_ healthy population, who likely
       | have a lifetime of exposure to exercise and physical activity. Do
       | the results here extrapolate to the general population? Do they
       | extrapolate to the same degree? It 's a decent question mark,
       | considering their results are non-significant in everything
       | except their "looks like false positives" brain volume measures
       | to begin with - even a little bit of "ehh... maybe not so much"
       | takes them into the realm of "no effects", alongside every other
       | measure in the paper. External validity is doubtful here.
       | 
       | 2. Internal validity is a bit doubtful too, first for reasons of
       | selection bias. They recruited 62 healthy volunteers; they had 14
       | dropouts. A 22% dropout rate isn't atrocious, but it's more than
       | enough - if it's not random - to skew a study. Their enrollment
       | figure describes the dropouts as almost entirely pre-
       | randomisation (10/14), but the study description notes that 6
       | drop-outs were due to failure to achieve frequency of adherence,
       | which clearly had to occur post-randomization, and 2 due to
       | dissatisfaction with group assignment (obviously post-
       | randomization). 6 got seriously ill - I'd love to know _in which
       | group_ , and with what.
       | 
       | 3. Their way of controlling for equivalent physical load was to
       | measure heart rate twice. On the one hand, not crazy. On the
       | other hand, if you've ever seen your HR during a workout session,
       | you'll see how noisy that is - and with a sample of a whole 38
       | pairs, that's a relatively huge amount of noise. Moreover, it
       | doesn't appear that they used that to guide intensity of
       | intervention, just "to control" (which I take to mean, to plug
       | into a multivariate model at some point - except they don't, as
       | they describe the covariates they plug into their model to be
       | age, sex, and intracranial volume for brain volume t-tests) I'm
       | skeptical this is an adequate control - I'd at least have wanted
       | a time-weighted average HR.
       | 
       | 3.b. The sports intervention had one effort-controllable
       | component (sport bike), but had 3 different components. It's not
       | at all clear they could capture the effort under the regimen
       | above, especially as the relatively light strength exercise that
       | the elderly tend to tolerate is the place where I'm most
       | suspicious of them failing to capture an effort delta.
       | 
       | 4. The differences in brain volume swung in different directions
       | in each group, without making an awful lot of sense (more right
       | cerebellar development in standard exercise group?? So,
       | asymmetrically, the less-coordination-demanding intervention
       | showed more development of the primary coordination center of the
       | brain?). But more generally, looking at supplementary table S3,
       | note that dancing showed improvements in anterior and posterior
       | white matter, and standard exercise in temporal and occipital.
       | The brain isn't that cleanly delineated - to find such
       | statistically strong effects in such broad brushstrokes sets off
       | a red flag for me.
       | 
       | The fact that there was scattered growth *in both groups suggests
       | we're looking at false positives. Not precisely a new problem for
       | this study methodology. Their p-threshold of .001 is considered
       | best-practices (aka, the bare minimum) for cluster-based
       | adjustment of multiple testing in neuroimaging: so that's good.
       | They don't report the p-values on their brain volume testing;
       | table S3 simply notes "p<.001". An actual effect size would be
       | better, but hard to get with cluster-based thresholds - they're
       | sensitive to "any signal, at all, is it there?" but they're
       | shitty at locking down precise volumes.
       | 
       | 5. Dance group had lower BDNF plasma at baseline vs. standard
       | exercise (1500 vs. 2100) (p .14), and equal at post (2200 to
       | 2100, p .6). In short, they showed regression to the mean in the
       | dance group. They report this as "the dance group had an increase
       | in plasma BDNF from baseline." Serum levels likewise were not
       | significantly difference pre and post between the two groups
       | (dance went from 35K to 36K, sport went from 30K to 29K). In
       | short, nothing happened. But they hid the "fucking nothing
       | happened" in supplementary table 4, and dressed it up real pretty
       | in the included figure 4.
       | 
       | 6. Cognitive outcomes, the only thing that actually matters here:
       | no differences.
       | 
       | 7. At least some physical fitness differences? No, none there
       | either.
       | 
       | TL;DR they found nothing, made some misleading figures out of it.
       | There are no perfect studies, but this one just boils down to
       | "found nothing, needed publication."

         | Even weight training, which is an experimental group in this
         | article, when done properly, requires high levels of neuro-

         | nothing repetitive about proper strength training. Every rep

         | 
         | Sports simply too complex to categorize in simple terms like

         | precise.
         | 
         | Having said all that, this is how I interpret this article:
         | "Learning complex motor skills that require high levels of

         | The belief that no knowledge exists outside of the scientific

         | unforced errors from the ability to reason about uncertainty,
         | like <everything our public health authorities have done during
         | the pandemic>.
         | 
         | I believe that the scientific method is the greatest engine for
         | rapid, high-quality knowledge generation in human history, and
         | consider its manifestation in the scientific establishment to
         | be one of the crowning achievements of humanity. But this
         | doesn't make its manifestation perfect: as with all human
         | systems, it's composed of people who are not immune to
         | pettiness, narrow-minded, selfishness, and even occasionally
         | stupidity. And as with all institutions, the human flaws of its
         | constituents are magnified 1000-fold due to the challenges of
         | incentive design and modeling large systems. Please note, this
         | is decidedly _not_ a criticism of scientists beyond "they're
         | human"; I wouldn't be surprised if the average scientist was
         | well below the median for all of the negative qualities I
         | described. It's just an acknowledgement that they're human,
         | they have flaws, and those flaws affect how science is
         | produced.
         | 
         | Proper science is vastly superior in efficiency and confidence
         | to many other forms of epistemology, but the imperfection of
         | the scientific establishment means that it occasionally
         | mishandles or abdicates responsibility for certain whole
         | sections of knowledge-space. In these situations, reasoning
         | under uncertainty requires cautiously looking at other sources
         | of knowledge; they may be "lower-quality" in many ways than the
         | scientific method, but they're better than simply assuming that

         | When I was younger, I had this insight in the context of
         | ayahuasca rituals while in Peru (I had the insight _before_ the
         | ritual, to be clear haha). The scientific community had
         | abdicated its responsibility to study the potential of
         | psychedelics for improving mental health; how else to interpret
         | shaman guiding an ayahuasca ritual than as an analogue of a
         | therapist[1] trained in psychedelic therapy, whose expertise is
         | shaped not through RCTs but centuries of trial and error? The
         | fact that the West is taking slow, halting steps towards
         | studying psychedelic therapy 70 years after its popularization
         | here is pretty damning, IMO: as somebody who treated science as
         | a valuable but flawed source of knowledge, I've been a happy
         | user of LSD for years, and consider it an immensely helpful
         | tool for mental health.
         | 
         | There are a million examples of this if you stop and think

         | the scientific establishment started studying it and now, it's
         | weird among some circles not to regularly do yoga and meditate.
         | This is again something you can learn easily through examining
         | "unscientific" tradition + self-experimentation, with an
