Intelligence and Age

It is widely believed that intelligence will fall with age, but this is a false idea. There are countless individuals claiming to have various cognitive processes related to brain changes that worsen over time, but there are other areas of the brain that increase their activity in old age. I think that the ability of a person performing a specific task may decline with age, but this does not mean that they cognitively decrease intelligence.

Mental collapse can also occur, causing dementia or disease such as Alzheimer's disease. Crystalline intelligence increases with age, but it is widely believed that liquidity intelligence decreases with age. Whether normal intelligence fluctuates with age depends on measures and research. Longitudinal studies have shown that perceived speed, inductive reasoning, and spatial positioning are diminished. An article on cognitive development in adults has been reported that cross-sectional studies have shown that "some abilities are stable at the initial stage".

Psychologist Raymond Cattell studied the two concepts of intelligence. Liquid intelligence is the ability of nature and can infer on the spot. It peaks at youth and then decreases with age. Crystallization intelligence is expertise in lifelong learning and skill accumulation. His paper is entitled "Age Difference in Fluid and Crystal Intelligence" co-authored with John L. Horn. Their work is the foundation of many IQ tests. The 2014 paper entitled "Myth of Cognitive Decline: Nonlinear Dynamics of Lifelong Learning" redefines the recognition of aging. We are often inaccurate due to forgetfulness (eg your grandfather forgot your name) and it may be a necessary consequence of brains filled with decades of learning information.

Why is human being so powerful? This is not our wisdom. The stone age human has the same brain power as the modern human being. However, as a stone age population, humans are vulnerable, vulnerable, and are facing many dangers. The power of modern people comes from the ability to cooperate in large groups. But trust is always a prerequisite for partners' cooperation. Whenever the confidence level between the parties is not sufficient, the solution is more centralized. For example, I personally do not know and trust all my neighbors, but this does not prevent us from coexisting peacefully. In order to realize this, we all need to fully trust the government and other central authorities such as banks and police. This may sound good, but it is clear that this idea has not even reached the national level, as well as the level of the region and the world.
