Understanding causality

Recently we have had some studies showing the remarkable intelligence of crows as problem solvers and their ability to use tools. Given this information, it was thought that they would also be good at inferring causal relationships. But as often happens, we find that intelligence is not a simple thing and that success in one aspect of it does not necessarily transfer to other areas.

Alvin Kallicharan vs Dennis Lillee

As part of my ongoing quest to convert readers of this blog into becoming cricket fans, I thought I would share a short clip from 1975 in which West Indian Alvin Kallicharan gives a gorgeous batting display. What makes this even more remarkable is that he scored these runs not off some journeyman bowler but against Dennis Lillee of Australia, a magnificent fast bowler who, along with Michael Holding of the West Indies, had the smoothest and best bowling actions that I have ever seen.

Spare me the sob stories

Jonathan Turley provides a good take-down of Hillary Clinton’s self-serving assertions in her new book, where she tries to minimize her culpability for endorsing the invasion of Iraq and tries to bond with economically struggling people by saying that she and her husband were ‘dead broke’ when they left the White House and had to struggle to pay their mortgage their daughter’s college tuition.

More scientists behaving badly

Science depends on its practitioners behaving ethically. This is important for three reasons. One is because scientists depend upon each other’s work and fraud in one area can really mess up the work of those who use those results. Another is because science has acquired a hard-won credibility with the public that has to be preserved so that those who deny the scientific consensus on important questions like climate change and vaccinations are not given ammunition to claim that science cannot be trusted. And the third is because much of science depends on public funding and that can be threatened by misconduct.

The obesity conundrum

America seems to be obsessed with the issue of obesity. Hardly a week goes by without this being mentioned as a serious public health crisis and that urgent measures need to be adopted to combat it. One can hardly blame people who do not fit into the perceived body-size norm for feeling beleaguered by society’s pressures and feeling that they have to take all manner of measures, even extreme ones, to try and lose weight. But as I wrote last year, there a lot of myths surrounding weight and weight loss that work against the idea that losing weight and keeping it off is a straightforward matter.

The open carry issue

The recent exploits of members of the group Open Carry Texas carrying massive guns around in public places and into restaurants and other business venues, and the reaction to it, has been a good example of how rubbing your rights into other people’s faces may not always be in your best interest. The best way to support the right of free speech may not be to stand on a street corner and talk to every person who passes by. Instead of being impressed by your commitment to upholding free speech, they are more likely to think you are a crazy person.

Computer passes Turing test for the first time?

[UPDATE: Other computer scientists are saying that the computer actually failed the test, and badly.]

People who have interacted with Siri, the helpful guide on the iPhone, are usually impressed with her ability to carry on what seems like a normal conversation. But it is not hard to discover that you are talking to a computer. How good would ‘she’ have to be to completely fool you?
