This is how it happens though. Some people are easy to convince with data alone, some are not, and others are simply in denial. Watch financial markets before a crash - lots of volatility while these groups are placing bets on the direction of the economy. Eventually we cross a threshold where the market crashes and all those that were unconvinced change their tune. It doesn't happen slowly.
