Actually Seed, that's not true - at least not for women.
They have done studies on that: at a job interview with
2 women, they offered the job to the more
attractive female even though the resume of the less
attractive female was considerably better.
Another attractive female was standing at the bottom of
stairs with a giant suitcase obviously trying to schlep
that thing up the stairs. Within seconds, several males
offered to carry the suitcase up the stairs for her.
The same test was done with a less attractive women
and nobody offered to carry her suitcase. She even
asked a guy if he'd help, and he said he had a back problem.
For us women, being attractive is definitely a plus, in
addition to being smart of course
