In view of Megan McArdle's recent comments about the laziness of teachers, I would like to point out Tom Levenson's recent post about her research problems. Mr. Levenson explains how McArdle links to a paper that disproves her own theory, namely that the nasty liberal academia is biased against conservatives and won't hire them.
We are left with two options: either McArdle read the paper and knew it disproved her theory and is a big, fat, lying liar who deserves to lose any credibility she might once have had, or she was too lazy to read the paper and had no idea that it refuted her entire thesis, thus making her look like an utter fool.
ADDED: In the past I have refrained from correcting her many spelling mistakes or criticizing her writing style. It seemed petty in view of the importance of her attacks on working people. I'll correct that error in the future. A person who is too lazy to click on spell-check deserves to have her errors pointed out.
