But Cambridge's
psychographic models proved unreliable in the Cruz presidential campaign, according to Rick Tyler, a former Cruz aide, and another consultant involved in the campaign.
Scott Tranter, a founder of the data - analytics firm Optimus who was on the data team for Republican Sen. Marco Rubio's 2016 presidential bid, told Business Insider that the
psychographic modeling that Cambridge Analytica touted «isn't
proven science» and that that was at least partially why some thought the service was nothing special.
