The secret to success in the Supreme Court revealed: Researchers say lawyers who DON'T have a masculine voice are more likely to win

Men who sound very masculine are less likely to win a US Supreme Court case than their gentler sounding peers, a new study has found.

Researchers analysed recording of laywer's voices and then asked volunteers to rank them.

They found that just one trait emerged as an indicator of how they would do - how masculine their voice was.
