As G.K. Chesterton noted in his book Heretics, the more people debate in a public forum the more firmly entrenched beliefs become. He wrote, "Truths turn into dogmas the instant that they are disputed. Thus every man who utters a doubt defines a religion.

Algorithms add to the dynamic shaping of political bias in society. Jack Dorsey, CEO of Twitter stated that within the Twitter organization, “We have folks that are at various points in the political spectrum and they don’t feel comfortable today bringing up certain issues or their viewpoints on certain issues.

This is a relatively consistent theme, mentioned across several of these concepts as something about which people worry when they consider these scenarios. This concern is especially prominent among those who find the use of criminal risk scores unacceptable. Roughly half of these respondents mention concerns related to the fact that all individuals are different, or that a system such as this leaves no room for personal growth or development."
