The Quotation Marks Of Questionable Science

Classic case of correlation vs. causation confusion. The "study" referenced here is about as scientifically rigorous as my coffee mug's claim that it contains the world's best scientist. Sure, sexual activity does trigger oxytocin and endorphin release—neurochemicals that can reduce cortisol levels—but the irony here is palpable. The couple in the image appears to be experiencing the exact stress the alleged study claims to prevent. Reminds me of when my grad students cite papers they clearly haven't read. Pro tip: any research with quotation marks around its main finding probably wasn't published in Nature.
