I was cruising Slate today, my typical source for keeping informed on current goodthink, and came across a few articles from that paragon of reasoned thought, David Weigel.

He provided an interesting lesson on what being a partisan hack for too long can do to a person’s brain.

At 2:03 pm, David  wrote about a Democratic ad that selectively quoted Romney on abortion. He said “so, yeah, that’s misleading.” He then goes on to justify it being misleading because it revealed something  he believed true about Romney.

At 9:25 am, David wrote about Republicans selectively quoting both Obama and Biden. His response, derision at gaffe-spotting and people are hyperventilating for thinking about it as it doesn’t reveal anything.

In less than five hours, he changed his opinion on selectively quoting politicians to mislead individuals from derision because its a waste of time to being justified because it reveals the truth.

Today’s lesson: Being a partisan hack can really damage your reasoning abilities.
