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

Is The Drone Strike a Black Swan?

Courtesy of Lee Adler

Pundits are calling yesterday’s drone strke a “black swan.” Can a drone strike on a Saudi oil facility, be a “black swan.”

According to Investopedia:

A black swan is an unpredictable event that is beyond what is normally expected of a situation and has potentially severe consequences. Black swan events are characterized by their extreme rarity, their severe impact, and the practice of explaining widespread failure to predict them as simple folly in hindsight.

I seriously doubt that no one expected or could have predicted a drone strike on a Saudi oil facility.

Crude Oil Cycle Bottom aligns with Saudi Oil Attack

Courtesy of Read the Ticker

Do the cycles know? Funny how cycle lows attract the need for higher prices, no matter what the news is!

These are the questions before markets on on Monday 16th Aug 2019:

1) A much higher oil price in quick time can not be tolerated by the consumer, as it gives birth to much higher inflation and a tax on the average Joe disposable income. This is recessionary pressure.

2) With (1) above the real issue will be the higher interest rate and US dollar effect on the SP500 near all time highs.

3) A moderately higher oil price is likely to be absorbed and be bullish as it creates income for struggling energy companies and the inflation shock may be muted. 

We shall see.

Despacito - How to Make Money the Old-Fashioned Way - SLOWLY!

Are you ready to retire?  

For most people, the purpose of investing is to build up enough wealth to allow you to retire.  In general, that's usually enough money to reliably generate a year's worth of your average income, each year into your retirement so that that, plus you Social Security, should be enough to pay your bills without having to draw down on your principle.

Unfortunately, as the last decade has shown us, we can't count on bonds to pay us more than 3% and the average return from the stock market over the past 20 years has been erratic - to say the least - with 4 negative years (2000, 2001, 2002 and 2008) and 14 positives, though mostly in the 10% range on the positives.  A string of losses like we had from 2000-02 could easily wipe out a decades worth of gains.

Still, the stock market has been better over the last 10 (7%) an...
