Beliefs, prejudices and data

Posted almost 9 years ago, 1 comment
When you see a bunch of things moving around in a flock on a pond in the distance, making quacking sounds, and occasionally becoming airborne, you do not ask for DNA evidence to determine that they are ducks, because you already have a lot of background information about swimming ducks.
