But there is a better reason to be skeptical of explanations relying on ideology. As a group, neither behavioral economists, who think that market efficiency is a joke, nor progressive economists, who distrust free markets, predicted the crisis.
当然，这些预期都会被理念所扭曲——但我们也无从追查经济学家们过去是如何思考的。而那些将原因单纯归咎于某种理念的解释也是站不住脚的，须知作为一个群体，无论是那些将市场效率视为笑话的行为经济学家；还是不相信自由市场的发展经济学家，都没能预测到这场危机。
