Fluid and crystallized intelligence

  • Fluid intelligence is the ability to reason, analyze, and solve unique problems. It is highest in early adulthood and diminishes in one's 30s and 40s.
  • Crystallized intelligence is the ability to use knowledge gained in the past. It relies on accumulated knowledge, tends to increase through one's 40s, and does not diminish until very late in life.

Careers that rely on fluid intelligence tend to peak early, while those that use more crystallized intelligence peak later. Profound insights tend to come from those in their 30s and early 40s. The best explainers of complicated ideas tend to be in their mid-60s unto well into their 80s.

Statistics

This is an invaluable tool for the fields of biology, medicine, economics, arts and humanities and the administrative services of the government.

Statistics provides useful tools, but those calculations and assumptions are based on certain constants that can lead to serious mistakes if taken too literally or applied to a large size. These calculations provide usable figures in a ‘quick and dirty’ way.

Adolphe Quételet's Estimations

Quételet, the mathematician turned astronomer who was performing social physics miracles as the central figure of Belgium science, got better in his game by learning probability theory and making use of his polymath brain. His work included estimations and calculations using the available data and his mathematical and statistical skills. Instead of counting everyone to know the population, Quételet used some reasonable estimates and then multiplied the number of births per year with the ratio of the total population to the annual births.

The new methodology was published in Quételet’s books in the 19th century, like Social Physics (1835) and its newer editions, and caught the imagination of the public. Concepts like the Average Man and the Bell Curve (a normal probability of distribution) simplified complex statistics and made it accessible to the world while being easily quotable and comparable.

Intelligence is not genius

Genius is not about having an extraordinarily high IQ, or even about being smart. It is not about finishing Mensa exercises in record time or mastering fourteen languages at the age of seven.

Geniuses and problem solving

Leonardo da Vinci believed you begin by learning how to restructure the problem by looking at it from many different angles.

In order to creatively solve a problem, the thinker should not use the usual approach that is based on past experience. Geniuses use several different perspectives to solve an existing problem and thereby also identify new ones.

Making your thoughts visible

_Galileo Galilei revolutionized science by making his idea visible with diagrams, maps, and drawings. Einstein believed that words and numbers as they are spoken did not play a significant role in his thinking process.

Geniuses seem to develop a skill to display information in visual and spatial forms, rather than only mathematical or verbal lines.
