EVP - Reputable Studies

My dad is a skeptic and won't believe in EVP until he sees that a reputable organization like MIT did a study on it. Does anyone know of any that have and can show me to the study results? Or are they just not interested and blame it on "suggestivity" or "external factors?"

Hmm, that sucks. I guess no reputable studies on it have been done. Why won't one of these places do it?
