The Diagnostification of Recent Horrible Biases

1.

Pitch-perfect, but untrue.

The ears are obvious.

Really? Are you sure? Would you like to investigate that?

The answer to which is no you wouldn't, they aren't absolutely.

2.

One category is like another.

For example, big ears are married to retarded.

No they aren't.

You forgot we're talking about an exception.

3.

He is far removed from the grounds (of science).

Not necessarily.

It depends on how exceptional he is.

4.

Physics is always right.

Not when the analogy you use is a plane doesn't fly because it has wings.

For an example of this false analogy, see Ryan Hendricks' comment (against Nathan, who has big ears) on the 'normal force'.
