Study leader David Puts said, “We find that masculine traits in humans are not the same as, say, in peacocks, where the beautiful tail attracts a mate. For example, beards make men more dominant-looking, scarier and seemingly more dangerous, but most women prefer clean-shaven men.”
For the first experiment, the researchers looked at 258 females and 175 male college students. The participants were recorded while reading a passage. The recordings were then rated by 558 women and 568 men. Each male recording was rated by women for attractiveness and by men for dominance. Overall, the recordings were rated more for dominance as opposed to attractiveness, implying that a deeper voice was associated with greater male dominance.
In an alternative experiment, researchers recorded 53 women and two groups of men with 62 in one group and 58 in the other. Their saliva was tested for cortisol and testosterone. For women, there was no correlation between voice pitch and cortisol or testosterone levels. In men, however, deeper voices were associated with low cortisol and high testosterone levels.
The findings were published in Proceedings of the Royal Society B.
