An experimental particle physicist who participated in the discovery of weak neutral currents. In a neutrino experiment, interactions without an outgoing charged lepton supplied a signature distinct from charged-current events. His participant account explains how event identification and backgrounds had to be controlled before the absence of a visible lepton could support a new interaction mechanism.[ref]

It seems like you might be referring to Jonathan Haidt, an American social psychologist and author known for his work on the psychology of morality, social behavior, and the dynamics of culture and politics. He is a professor at New York University and has written several influential books, including "The Righteous Mind: Why Good People Are Divided by Politics and Religion" and "The Coddling of the American Mind" (co-authored with Greg Lukianoff).
