Quite naturally I would imagine it makes you more competent in every role where you can be discriminated on those basis (customer-facing, or any job that's heavy on communication). Could make sense for the social worker role, less so for the IT specialist, but I'd be interested to know your source.

I'm hoping he comes up with a source too, but I imagine that the people we're all naturally biased toward generally get evaluated in the most favorable light so it'd be weird if there wasn't some data that showed they were more competent.
