Why is it surprising that scientists might have long hair and wear cowboy boots? In fields like neuroscience, where the events you are recording are so minute, I suspect scientists cultivate a boring, reliable image. A scientist with a reputation for flamboyance might be suspect.

There's a misconception that survival of the fittest means survival of the most aggressive. The adjective 'Darwinian' used to refer to ruthless competition; you used to read that in business journals. But that's not what Darwinian means to a biologist; it's whatever leads to reproductive success.

Boxing is like chess. You encourage your opponent to make mistakes so you can capitalise on it. People think you get in the ring and see the red mist, but it's not about aggression. Avoiding getting knocked out is tactical.
