Omega-3 lesson: Not so much brain boost as fishy research

This is a good article highlighting how scientific research gets misrepresented in the media, making it important to go to the original source.  Moreover, often an experiment measures one thing (a surrogate) but makes conclusions that go well beyond what was actually measured. (E.g. high cholesterol levels being used as a surrogate for heart attack risk.) – Ilene 

Omega-3 lesson: Not so much brain boost as fishy research

By Ben Goldacreguardian.co.uk

Fish oil helps schoolchildren to concentrate ran a headline in the Observer. Regular readers will remember the omega-3 fish oil pill issue. The entire British news media has been claiming for several years now that there are trials showing that the pill improves school performance and behaviour in mainstream children, despite the fact that no such trial has ever been published.

There is something very attractive about the idea that solutions to complex problems in education lie in a pill.

[...]

This paper showed no difference in performance at all. Since it was a brain imaging study, not a trial, the results of the children’s actual performance in the attention task was only reported in a single paragraph. But these results were clear: "There were no significant group differences in percentage correct, commission errors, discriminability, or reaction time."

So this is all looking pretty wrong. Are we even talking about the same academic paper? I’ve a long-standing campaign to get mainstream media to link to original academic papers when they write about them, at least online, with some limited success on the BBC website. I asked the writer Campbell which academic paper he was referring to, but he declined to answer, and passed me on the Stephen Pritchard, the readers’ editor for the Observer, who answered a couple of days later to say he did not understand why he was being involved. Eventually Campbell confirmed, but through Pritchard, that it was indeed a paper from the April edition of the American Journal of Clinical Nutrition.

[...]

Similarly, drug reps and researchers will often announce that their intervention has some kind of effect on some kind of elaborate measure of some kind of surrogate outcome: maybe a molecule in the blood goes up in concentration, or down, in a way that suggests the intervention might be effective.

This is all very well. But it’s not the same as showing that something really does actually work back here in

There Are 3 Main Theories That Explain Trump's Approach to Putin and Russia-Which One Makes the Most Sense?

What do you think?

Thom Hartmann suggests that the "Manchurian Candidate theory" is the least likely explanation for Trump's pro-Russia behavior in "There Are 3 Main Theories That Explain Trump’s Approach to Putin and Russia—Which One Makes the Most Sense?" (below).  disagrees and suggests that Putin probably has "the goods" on Trump in "Trump’s Plot Against America".

Mapping The Market

Mistakes were Made. (And, Yes, by Me.)

Via Jean-Luc:

Famed investor reflecting on his mistakes:

Mistakes were Made. (And, Yes, by Me.)

One that stands out for me:

Instead of focusing on how value factors in general did in identifying attractive stocks, I rushed to proclaim price-to-sales the winner. That was, until it wasn’t. I guess there’s a reason for the proclamation “The king is dead, long live the king” when a monarchy changes hands. As we continued to update the book, price-to-sales was no longer the “best” single value factor, replaced by others, depending upon the time frames examined. I had also become a lot more sophisticated in my analysis—thanks to criticism of my earlier work—and realized that everything, including factors, moves in and out of favor, depending upon the market environment. I also realized...
