Individuals spend immense mental energy worrying about judgment. Erasing this knowledge cures the chronic anxiety born from trying to read minds and manage impressions.
A world where individuals cannot know how they are perceived by others would not be bad. People would stop worrying about their impressions and actions as they are unable to guess others mind. Less mental diseases more happiness in the world.
A world without the ability to know how others perceive us would eliminate concerns about external impressions, fostering greater mental well-being and happiness.
