In recent years there have been investigations that try to corroborate whether we can talk about left and right brains. In 2013, an experiment carried out by scientists from the University of New York and the University of California (UCLA) was published in which the relationship between a certain political orientation and the way in which the brain processes information was demonstrated.
That same year, from the United Kingdom, a team from the University of Exeter worked together with the University of California at San Diego observing the differences in the functioning of the brains of citizens of the United States, Republicans and Democrats. Although the behavior of Democrats (liberals) and Republicans (conservatives) did not differ, their brain activity did.
And now, studies in the US and Israel do identify differences in the way left and right brains react. "To the same political stimulus, different brain response depending on these political ideas," says scientist Yaara Yeshurun-Dishon.
It has been shown that ideology is marked in the brain. Our political thought is evidenced by analyzing the functioning of the brain with artificial intelligence. What is not yet known is whether this brand of the brain generates ideology or, conversely, whether our political preferences influence and shape our brains. Thrilling.
Studies on the brain and debates on the impact of science in shaping it, directly intervening with technology or supplanting it with artificial intelligence will be decisive in a new challenge for democratic politics. We risk the freedom that is born of free will. Ethical issues will challenge our enormous technical capacity. Neuroscience must become neuroethics or it will overwhelm us.
Meanwhile, it has been shown that the heart contains its own nervous system that allows it to make decisions independently and is capable of influencing our perception of reality and the way we react and behave. We think (and vote) with our hearts, too. In the end, it is emotions that make us human. That will be the last bastion of humanity.
