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

Weekly Market Recap Dec 09, 2018

Courtesy of Blain.

Bears are certainly showing the type of strength we haven’t seen in a long time.   A week ago at this time futures were surging on news of a “truce” for 90 days between China and the U.S. in their trade spat.  But the charts were still not saying lovely things despite a major rally the week prior.   And by Tuesday, darkness had descended back on the indexes, with another gut punch Friday.    A lot of emphasis was put on a long term Treasury yield dropping below a shorter term Treasury.

On Monday, the yield on five year government debt slid below the yield on three year debt, a phenomenon which has p...

Dollar Slides After Goldman Capitulates, Pulls March Rate Hike Forecast

Courtesy of ZeroHedge. View original post here.

For months, Goldman's optimistic take on the economy drew raised eyebrows across both the sell and buyside, and nowhere more so than the bank's forecast for 4 Fed rate hikes in 2019, a number that is even higher than the Fed's own dot plot forecast which anticipates 3 rate hikes next year, not to mention the market's own implied prediction of less than 1 rate hike in the coming year.

Well, on Sunday night Goldman capitulated and in a note titled "The Ides of March" published late on Sunday by Jan Hatzius, the banks capitulated on its o...

Small caps could fall 20% from here, says Joe Friday

Courtesy of Chris Kimble.

This chart looks at the Russell 2000 over the past 30-years, where it has spent the majority of that time, inside of rising channel (A).

This chart reflects that the long-term trend in small caps remains higher. Weakness this year has it testing rising support tied to the 2009 lows at (1).

Joe Friday Just The Facts Ma’am- If the Russell breaks below support at (1), it could work its way over time to channel support at (2), which is currently around 20% below current prices.

Very important support test in play ...

Cheri Jacobus on Politics with PSW

 

Cheri Jacobus is a widely known political consultant, pundit, writer and outspoken former Republican and frequent guest on CNN, MSNBC, FOX News, CBS.com, CNBC and C-Span. Cheri shared her thoughts about the current political environment with us in our August interview, and now we’re following up. 

Ilene: Is there a take-home message from election results of 2018?

Cheri: Yes. No political party can survive when it appeals to only one demographic. The GOP has ignored all of the lessons of recent elections that showed they needed to appeal to African-Americans, Latinos, and women. 

Ilene: Do you feel the Democrats ...

The Vilas Fund, LP letter for the third quarter ended September 30, 2018; titled, “A Bull Market in Bearish Forecasts.”
