Privacy International self-owns

Privacy International should feel remorse about walking right past several other companies to single out Google for their lowest rating. But I think that there’s a larger danger here too. I believe this report could corrode earnest efforts to improve privacy at companies around the internet. Why? Because the bottom-line takeaway message that I got from the report is that a company can work hard on privacy issues and still get dragged into the mud.

What A Change in 35 Years

David Schonauer of American Photo has uncovered a rather stunning coincidence, the picture that’s been making the rounds of P.H. being hauled back to jail was taken by none other than Huynh Cong “Nick” Ut. Nick Ut, as you remember from Photo History 101, was the photographer who took one of the iconic pictures of the Vietnam war, the picture of Kim Phuc running naked down a country lane after suffering serious napalm burns. Ut’s photograph was arguably the apex of the notion of “The Concerned Photographer,” Cornell Capa’s phrase for the idea that photographs of injustices and atrocities could help correct the situations that led to them. And get this: the 2 pictures were taken exactly 35 years apart, to the day. Quite a coincidence.

ah the irony

Research is false

There is increasing concern that in modern research, false findings may be the majority or even the vast majority of published research claims. However, this should not be surprising. It can be proven that most claimed research findings are false.

Ioannidis presents a Bayesian analysis of the problem which most people will find utterly confusing. Here’s the idea in a diagram.


Suppose there are 1000 possible hypotheses to be tested. There are an infinite number of false hypotheses about the world and only a finite number of true hypotheses so we should expect that most hypotheses are false. Let us assume that of every 1000 hypotheses 200 are true and 800 false.

It is inevitable in a statistical study that some false hypotheses are accepted as true. In fact, standard statistical practice guarantees that at least 5% of false hypotheses are accepted as true. Thus, out of the 800 false hypotheses 40 will be accepted as “true,” i.e. statistically significant.
