Both religion and gambling involve magical beliefs and irrational optimism about one’s own personal future. People younger than about 26 have not yet completed full brain development, particularly in the region responsible for judgment. They expect to win more often than the actual odds dictate. Young men are more prone to risk-taking and are likely to have more opportunities for, and interest in, sports betting than other forms of gambling. High income allows them to indulge in these activities more readily as well.
