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

Amid an ever-escalating guess at the size of pension fund re-allocations funds (latest we saw was $150 billion) into month-end, both bonds and stocks were bid early on today, but as the day wore on, bonds weakened as stocks gained (driven by record IG issuance-driven rate-locks)...

I put together this video that will calm you down, because knowing where are within the stock market cycles, and the economy makes all the difference.

This is the worst time to be starting a business that’s for sure. I have talked about this is past videos and events I attended that bear markets are fantastic opportunities if you can retain your capital until late in the bear market cycle. If you can do this, you will find countless opportunities to invest money. From buying businesses, franchises, real estate, equipment, and stocks at a considerable discount that would make today’s prices look ridiculous (which they are).

Take a quick watch of this video because it shows you ...
