Retarded thread. Dark triad is extremely beneficial to all aspects of your life, that doesn't just mean dating and sex. Sure someone who is extremely hideous probably won't ascend even if he's dark triad, but socially he will be far better off than someone of the same looks level who isn't. Part of why dark triad personality is very effective is because it makes you charming, likable and extroverted, which initially attracts most people to you, combined with high social intelligence and the attitude of doing whatever it takes to achieve one's goals, they gain very high social status and power, making them practically invincible.
TLDR: Someone who's dark triad will always have high social status, and a ton of friends who like and respect them, they will likely have a high paying job and be in a position of power, most of them will have an easy time ascending.
