香水

作為economist的讀者,我最感興趣的其實不是他們的政治經濟文章,而是那些科學研究的擇要。

一直以來,我都以為香水商其實不是賣液體,而是賣廣告和瓶子的。還真的不知道原來香水也是有實際功能的。

研究讓部分男人涂了香水,然后放他們的靜默短片給女人看,那些女的又真的覺得他們比較有吸引力(因為看起來比較有自信). (照片無效,所以跟外表無關)。

女的用香水原來是為了加強自己的‘氣味信號’。 這些信號包含了人的某些基因信息。 而人通常會受不同類的吸引,這樣才有利于下一代的基因。

根據這些理論,我們盡量不應該挑送香水送人,就算要送也要選那些自己不喜歡的。

科學很好很強大...乜都可以研究出啲東西...囧
話說睇過一篇研究文章,講說金融機構內的男性右手無名指長過食指越多賺嘅錢亦越多

their selection of papers on science look random but is actually intentionally biased. i remember once they cited an unpublished working paper instead of 500 published ones who argue the opposite.
since then on i don't trust their pick of academic papers.

well the study cited in the first comment is pretty much random correlation unless there's generic proof. if you don't control anything and just run a simple time-series regression, you could possibly find economic growth perfectly correlated with the population of squirrels in the region, or anything else.
