One problem I have seen is that when science is used, people in charge reject the science. One common example is the risk of sex offenders re-offending. It is well known that sex offenders are at a vastly increased risk of offending again. That is also quite false. What data there is on those who re-offend show that sex offenders have some of the lowest rates of recidivism, but people are so conditioned by the incorrect narrative that they reject the science. This includes not just the average person voting for a politician who will make worse laws, but also the people involved in the legal system who decides who gets parole, who gets probation, and how long should sentences last.
