Dr. Richard Peterson, a founder of MarketPsych, a hedge fund that makes investments based on neuro-economic research, just happened to be in our studios when news broke that the House had voted down the financial bailout bill.

Peterson, who is also a practicing psychiatrist, told Marketplace Money Host Tess Vigeland that Americans and congressional representatives were more concerned about exacting revenge than taking action that would set the financial markets on the road to recovery.

Here's a portion of his interview with Tess.

More from that interview will be on Marketplace Money this weekend.
