From PLOS One, Testosterone Administration Reduces Lying in Men:
In a double-blind placebo-controlled study, 91 healthy men (24.32±2.73 years) received a transdermal administration of 50 mg of testosterone (n = 46) or a placebo (n = 45). Subsequently, subjects participated in a simple task, in which their payoff depended on the self-reported outcome of a die-roll. Subjects could increase their payoff by lying without fear of being caught. Our results show that testosterone administration substantially decreases lying in men.
Individuals were dosed with testosterone or placebo and asked to roll the die once, then were payed a few euros (or not) based on the results of that roll. The researchers evaluated honesty of each group based on the collective payouts. Interestingly, the "juiced" group was quite a bit more honest.
Now, far be it from me to point and smirk while "integrity of the game" types wrap their collective heads around the possibility that illegal steroid usage could make baseball a more honorable game on the field. I am convinced now more than ever, though, that in The Bizarro World, PEDs are legal and everyone is just as obnoxious and pious about their respective views on the matter. Sportwriters write long diatribes criticizing non-juicing Eckstein-types:
…some say he doesn't have the commitment to his team, rarely lifting weights after games and between innings… has a questionable moral compass as evidenced by the frequency with which he steals second, not having earned it with an extra base hit… instead of trying to hit the ball as far as possible as was intended by Doubleday, he occasionally taps it in front of home plate and tries to scamper to the first base…
Meanwhile, bizarro bloggers defend the collectively-bargained rights of the players not to use steroids, while suggesting that maybe it's time to hire an unbiased third party to make judgement calls about balls and strikes instead of relying on the honor system.
