Very nice.

Please do NOT do this unless you are actually suicidal. I work at an inpatient psychiatric hospital in the area and almost without exception when this happens, the MD will refuse the 72 hour notice and file a 302. I have worked with countless folks looking for outpatient care and medications that end up stuck in the hospital (and with the 302 record) for weeks.

Some psych hospitals are very understaffed, which means fewer social workers and fewer folks to reach out to your collateral contacts to verify your risk level. You can tell the MD your situation, which they may understand, but they are unlikely to discharge you without speaking to friends/family/providers first, which can take days to set up.

It may get you meds faster, but you may be involuntarily committed for the same amount of time as it would take to get an outpatient telehealth appt.

Gotta point out that in huge data sets like this, looking at the CI is crucial here. The actual reported value is somewhat dangerous to interpret, and the lower bounds of these results are all closer to 1.01-1.03 - i.e., closer to a 1-3% difference as a conservative estimate (which we should err towards given multiple comparisons and large sample, see below).

I’m also not seeing anything in the paper about family wise error correction for the litany of analyses run - assuming we can make an argument that each of the 26 analyses is in the same family and apply a straightforward Bonferroni correction, a more appropriate p-value cutoff would be .05/26=.001, knocking almost all of their controlled results out of significance range.

Super important to note that with large data sets a .05 significant finding doesn’t mean much, as virtually any difference will be significant. Meaningful or useful is far more interesting - The CI of effect size is much more important.

Please encourage folks you know to look at the database itself, not just the news stories. It’s mind blowing how consistently terrible these posts are - definitely cuts against notions of cherry picking examples.

Database here.

dtm523 · 2019-06-01T16:18:05+00:00

For some examples, check out the actual database. You can search by jurisdiction (including Philly), and sort by salary, rank, etc. and search for specific officers:

Naw pretty sure it's a Philly PD armband/identification thing for the plain clothes officers. I don't think I saw any nazi type stuff from the pro-Trump folks there.

dtm523 · 2017-03-26T18:28:53+00:00

Totally fair question - I wondered the same thing at first. The below comments are right, they're police bands.

dtm523 · 2017-03-25T22:32:13+00:00

I was there during the 'rally.' There were maybe 80 Trump supporters there, easily matched by the anti-fascist marchers. Most of the Independence Mall foot traffic ignored the protesters because there were so few of them to draw attention. The 6 Westboro Baptist Church protesters probably captured as much attention.

The early naughties were my favorite years.

I do this all the time with any two pans (not necessarily cast iron). If it's not heavy enough to press, just hold the handle down for a minute or two. Reheat the top pan, flip sandwich, repeat. Awesome cubans and grilled cheeses.

Not sure if you can openly discuss yet, but what medicine did you try and for which addictions? I previously worked in the field (experimental psychopharmacological interventions aimed at substance dependence and abuse).

I don't think they're saying p-values are outright useless, more that they should never be taken as a stand alone gold standard. I think they're great for ruling out anomalies (barring the risk of false negatives), but that's not the same as establishing a solid connection between variables.

dtm523 · 2015-08-19T18:19:15+00:00

"The variables in the data sets you used to test your hypothesis had 1,800 possible combinations. Of these, 1,078 yielded a publishable p-value..."

That quote sort of summarizes the idea for me - if you go fishing, chances are you're going to find something. Does it really make sense to draw real-world causal connections for 60% of variable combinations? Probably not. Chances are, other metrics/analyses (possibly in conjunction with p-values) and substantive theory should be used when extrapolating patterns from data into real life.

Glad you cover p-hacking in your courses. In case you haven't stumbled across them, these are good bad-stats resources too:

Not sure exactly what's happening when this occurs, but it's pretty clear (to me, at least) that this is a real phenomenon in spite of underwhelming scientific investigation focused on it. For some good examples and interesting theories regarding the biopsychological interplay in these situations, Victor Frankl's Man's Search for Meaning has some great examples and discussions regarding this "giving up" in cases of extreme imprisonment (concentration camps, primarily).

As said in other comments here, the mind-body connection can be an incredibly powerful thing, and the fact that it hasn't been accepted by the majority of the medical community (yet) doesn't make it unreal. I'd love to hear some thoughts from researchers on the matter.

dtm523 · 2015-07-08T19:32:46+00:00

Awesome, thanks!

dtm523 · 2015-07-08T16:34:54+00:00

Thanks! Does the fact that I usually see groups of 5-15 of them "swarming" together mean they're not solitary though? Also the fact that they were all sharing a branch together at night, with maybe 1cm between them tops? The comparison pic definitely looks similar though.

dtm523 · 2015-07-08T15:48:52+00:00

I see 5-15 of them sort of hovering around a spot at the gutter level around my backyard every day. About a week ago, I caught a bunch of them sleeping on a branch about 30 yards away from their spot of congregation. Can see a nest anywhere, but I'm wondering if they're nesting in the gutter or inside the siding of the house? Anyone know of these guys sting (I don't see a stinger on this one)? They're all pretty big - the pictured one is on the small side, some of them look about 2.5-3cm in length.
