Whoever posted this article they way they did at Slashdot should be ashamed to call themself a nerd. First, there is no mention of isolating the causes of unhappiness -- just the most broad kind of correlation. Second, math is work. Achievement in math is hard work. Anyone expecting short term happiness (happiness achieved during the school years) from hard work is just plain unrealistic. But, the study doesn't even answer the question as to whether or not those math students are happier later in life. I've personally always believed that smart people face tougher childhoods and easier adulthoods, and that the tradeoff of the effort is worth it. Why promote this article the way you're promoting it here? It's terrible science and headlined in much the way newspapers headline studies in ways that get people to read the headline, say "uh huh", then never read the article or think about whether or not there's something to the story. A better headline would have been "Another Researcher Gets Paid for Useless Study". This whole mess would have made a better Onion article.
