Interesting article from Mother Jones:
The researchers conducted three experiments in which students were asked to purchase or evaluate green products, or buy conventional ones, and then participate in an “unrelated” task. In each experiment, students who didn’t buy green products acted more altruistically and honestly in the second task than those who did. In the words of the researchers, “people act less altruistically and are more likely to cheat and steal after purchasing green products as opposed to conventional products.” However, if you consider that 98 percent of so-called “green products” are based on misleading claims, then that moral high ground is even shakier. – from MJ
