People often talk about the male-female wage gap, but there's not much talk about the wage gap between the tall and short. This study seems to support that shorter people are indeed held back in regards to workplace success.

Abstract
Taller workers earn on average higher salaries. Recent research has proposed cognitive abilities and social skills as explanations for the height-wage premium. Another possible mechanism, employer discrimination, has found little support. In this paper, we provide some evidence in favor of the discrimination hypothesis. Using a cross section of 13 countries, we show that there is a consistent height-wage premium across Europe and that it is largely due to occupational sorting. We show that height has a significant effect for the occupational sorting of employed workers but not for the self-employed. We interpret this result as evidence of employer discrimination in favor of taller workers. Our results are consistent with the theoretical predictions of recent models on statistical discrimination and employer learning.

Those who tell short people "it's all in your mind" need a wake up call.
