Steven Pinker on the risks of riding a bike

From the NY Times Magazine:

....Steven Pinker's latest book, “Rationality: What It Is, Why It Seems Scarce, Why It Matters,” takes on another provocatively large subject and will be published on Sept. 28. 

“Many philosophers that I know,” says Pinker, “think that the world would be better if more people knew a bit of logic.”

Are there aspects of your own life in which you’re knowingly irrational? 

The answer is almost certainly yes. I probably do things that morally I can’t justify, like eating meat. I probably take risks that if I were to do the expected-utility calculation could not be justified, like bicycling. 

If I were to multiply the probability of my being killed by the value placed on my life, it would certainly be less than the same sum for getting my exercise by hiking or swimming. 

But nonetheless I enjoy bicycling. I try to mitigate the risks and to adjust my behavior to make it more ethically defensible. I have reason to believe at a meta-self-conscious level that whatever adjustments I do make are probably less than what would be optimal.
