Although the media and some activists are determined to show only the negative examples or see the glass half empty, the truth is that there are fewer and fewer racists, sexists and homophobes in the world.
We know this because, since 1981, a worldwide network of social scientists and political scientists conducts research, conducting representative national surveys in almost 100 countries, that is, surveys of more than 150,000 people. statistically covering 90 percent of the world's population.
World Values Survey
The World Values Survey (WVS), which is what it is called, allows us to warn that moral values are getting better, as if a germ of very powerful prosociality is nesting in us, especially in the more developed nations (North America, Western Europe and Japan) .
The WVS measures, observes and analyzes: support for democracy; tolerance towards foreigners and ethnic minorities; support for gender equality; the role of religion and changes in levels of religiosity; the impact of globalization; attitudes towards the environment, work, family, politics, national identity, culture, diversity, insecurity and well-being of the individual. As explained by the cognitive psychologist Steven Pinker in his book In defense of the Enlightenment:
The data show that the most liberal countries are also, on average, more educated, more urban, less fruitful, less inbred (with fewer marriages between cousins), more peaceful, more democratic, less corrupt and less punished for criminality and for the coups.
That would also explain how it is possible that, under the appropriate context, we become so sociable that this is allowing to reduce homicides throughout the world, as the history professor points out. Yuval Noah Harari in Homo Deus:
While in ancient agricultural societies human violence caused about 15 percent of all deaths, during the twentieth century violence caused only 5 percent, and at the beginning of the twenty-first century it is responsible for about 1 percent of global mortality.
Thus, it is possible, and this is quite reasonable, that we have evolved psychologically to be prosocial, like a wolf becoming a dog, thanks to memetic pressure. And that is why we are going to get better, despite the media struggling to make a cherry picking to show only negative news.
