Slashdot 上的 Study Finds Value in Email Spam 這篇文章是說，研究員找了大約 2100 個加拿大人，分成兩組，其中一組每個禮拜都會收到「減肥對於身體健康好處」的廣告信，而另外一組則不會收到。在進行了十二個禮拜後，收廣告的那組 BMI (Body Mass Index) 平均值降低了。

但這代表什麼？廣告信與身體健康有幫助嗎？不，這只證明了：如果有人告訴他們關於「減肥對身體健康的好處」，那麼他們就會試著去做。

所以下面的 comment 寫的很諷刺，直接挑明了這篇垃圾論文只是在混淆視聽：(我只引用了前半段)

You know what else is good?

If you have a fat wife or fat children, you should tell them they’re fat several times a day. And tell them they need to lose weight. And do it in front of company when people visit. And when they’re at the dinner table, tell them they don’t need seconds when they reach for something, because they’re fat.

And tell your daughter she’s ugly, so she’ll do something about her face and maybe get some cosmetic surgery. And tell your son how stupid he is every chance you get so he’ll be compelled to be an educated man.
