Excellent topic and analysis of what you very well call "collective ignorance." You will know that it is one of the reasons why I call my children's attention many times, since I frequently notice that they pay too much attention to superfluous things that They do not really matter, sometimes I think that happens as a result of the impetus boom in the world with the new technologies ... Before, my generation, we did not have a telephone to communicate with others, so life went more slowly, and we could be more analytical and deepen in our perception of things.Today there is an excess of information from all sides, but most of them in quantity rather than in quality, it will be a task of all the teachers, counselors and parents of the world to call the attention of our young people in that sense, thanks for sharing.
