I didn't 'make a bet' by going to college, it was the assumed thing in my family, it was culturally ingrained that I would go to college. This way of looking at life as a series of 'bets' that one makes is it's own particular kind of culture, one that Newton did not belong to.
Newton didn't investigate alchemy and theology because he was trying to diversify his fame investment portfolio. To see him this way is to do a disservice to him and to history.
