The reason the human brain is more complex and sophisticated than that of other primates is to facilitate the establishment of social relationships. The brain develops through the senses, and humans must experience them to sense. Without experience, the human brain cannot perceive. All social experiences contribute to the development of a social brain. The broader the relationships, the more socialized the human brain becomes. Through experience, the human brain can compare and organize information to communicate effectively with other brains. To empathize, we mirror the brains of others. Who we are with is also neurologically essential. - Joseph’s “just my thoughts”
Even though a country's total population is decreasing, the economic situation could be improved by increasing the total economic activity of the remaining population after the decrease. Of course, there is a statistical population threshold below which this effect occurs. Nevertheless, this effect would not work in the case of a force majeure, such as a natural disaster or the outbreak of war, however, this assumption would be valid because a rapid population decline is a highly exceptional event that would not normally occur. Therefore, an increase in the economic activity of this population should be required during an economic recession. Applying this perspective, for building a solid relationship with your followers on Instagram, the number of followers is less important than the activity between them and you. This is called the "Engagement Rate (ER)". - Joseph’s “just my thoughts”
