Data dredging is fairly common in health research, and especially in studies involving food. It is one reason contradictory nutrition headlines seem to be the norm: One week coffee, cheese and red wine are found to be protective against heart disease and cancer, and the next week a new crop of studies pronounce that they cause it. Marion Nestle, a professor of nutrition, food studies and public health at New York University, said that many researchers are under enormous pressure to churn out papers. One recent analysis found that thousands of scientists publish a paper every five days.
I liked this:
“P-hacking is a really serious problem,” said Dr. Ivan Oransky, a co-founder of Retraction Watch, who teaches medical journalism at New York University. “Not to be overly dramatic, but in some ways it throws into question the very statistical basis of what we’re reading as science journalists and as the public.”
You don’t say.
It goes far beyond nutrition. A lot of drug research is based on this sort of thing as well, including the statin scam.
Few, if any, dispute that atmospheric CO2 levels have been increasing since the industrial revolution. What is in dispute is the effects of this. The prevailing media narrative is that “OMG we’re all gonna die!” but this is an interesting post.
I flew from PBI to LAX last night, partly because I needed a break and wanted to be home, but mostly because corporate taxes are due on Monday. And I’m going to Orlando Sunday for the AIAA meeting, then back down to south Florida, hopefully to finish things up at the house, and finally (a year after we started, and were interrupted by Hurricane Irma) get it on the market and sold.
There is a Greek myth, which may or not be true, that @n@l sex is called “Greek” because the ancient Greeks used it for birth control. Well, a clueless couple in China failed to get pregnant for four years because they were doing it wrong. At least for that purpose. Hopefully they were at least having a good time.
It’s about 0230 EDT, and I’m still up, planning home renovations for tomorrow. But I’m in south Florida, about fifteen minutes from the swamp to the west, and the sky is clear for both the Perseids and the Parker Solar Probe Delta IV launch in an hour, 150 miles north-northwest of me. So I might as well stay up a little longer. Hoping I’ll see the Milky Way for the first time in a long time.
[Sunday-morning update]
Well, saw half a dozen meteors, one of them right next to the ascending rocket. No Milky Way, though.
[Update Sunday night]
Given my recent failed attempts to see it, I’m wondering (slightly depressed) if it’s an age-related vision decline. It was very distinct in my youth, but it seems like there are a lot fewer stars than there used to be.
Marina Koren has the story, with a quote from Yours Truly. It launches at 3:30 in the morning, not sure if I’ll have the gumption to get up to watch from Palm Beach (or worse, drive up to the Cape). On the other hand, if it’s clear, should be lots of Perseids visible then, since it’s a new moon.
A new mountain lion has been spotted in the Verdugos. It’s interesting that LA is so big and geographically diverse that it can have not just parks within it, but a wilderness. Unfortunately, urban encroachment is going to make it harder and harder for these animals to make it there. They’re building a tunnel under the 101 to allow them to move back and forth between the Santa Monicas and the mountains above Simi Valley and Thousand Oaks, but I’m not sure if it will be sufficient, and it looks like they need one under the 210 to allow safe passage between the San Gabriels and the Verdugos.
