NATO Alliance has joined the 'battle for the brain', developing new forms of warfare combat tactics for use in 'cognitive warfare' to 'make everyone a weapon'. This cognitive warfare is described as the weaponization of brain sciences. The new method involves “hacking the individual” by exploiting “the vulnerabilities of the human brain” in order to implement more sophisticated social engineering in the human domain. Take a look at the 2020 Nato-study published as a 45-page report in January 2021 (PDF) link in article.

Data/information capture has been used to identify the human markets to sell products and services, effect politics/election interference & outcomes (i.e. Cambridge Analytics), social media impact on society and cyber-warfare. This has has given rise to the term captology which is 'the use of computers as persuasion technology'. The data economy is in actuality a behavioral economy.

But what are the long-term impacts of technology on the brain? Dr. James Giordano claims, “the brain will the battlefield of the 21st century”. When it comes to shaping the brain, the technological environment plays a key role. The brain has only one chance to develop. Damage to the brain is very often irreversible. Understanding and protecting our brains from external aggression, of all kinds, will be one of
the major challenges of the future. According to the neuroscientist Maryanne Wolf, humans were not meant to read and the invention of printing changed the shape of our brains . It took years, if not centuries, to assess the consequences - social, political or sociological for example - of the invention of printing. It will likely take longer before understanding accurately the long-term consequences of the digital age but one thing everyone agrees on is that the human brain is changing today faster than ever before with the pervasiveness of digital technology. There is a growing amount of research that explores how technology affects the brain. Studies show that exposure to technology shapes the cognitive processes and the ability to take in in-formation. One of the major findings is the advent of a society of ‘cognitive offloaders’, meaning that no one memorises important information any longer. Instead, the brain tends to remember the location where they retrieved when it is next required. With information and visual overload, the brain tends to scan information and pick out what appears to be important with no regard to the rest. One of the evolutions already noticed is the loss of critical thinking directly related to screen reading and the increasing inability to read a real book. The way information is processed affects brain development, leading to neglect of the sophisticated thought processes.

Food for thought in a society that grows more dystopian by the day.
