Galton’s intensive use of measurement methodologies led him to discover and establish fingerprinting as a reliable method of identification. Having collected hundreds of fingerprint samples, Galton created a taxonomic classification system still largely in use by forensic scientists of the twenty-first century.

Measuring Intelligence
He believed that many aspects of human nature, including intelligence, could be measured scientifically. ... tests, Galton attempted to measure intelligence through reaction time tests . For example, the faster someone could register and identify a sound, the more intelligent that person was.

Thus, if a 10-year-old child had a mental age of 12 (that is, performed on the test at the level of an average 12-year-old), the child was assigned an IQ of 12 / 10 × 100, or 120. If the 10-year-old had a mental age of 8, the child’s IQ would be 8 / 10 × 100, or 80.

Many aspects of fluid intelligence peak in adolescence and begin to decline progressively beginning around age 30 or 40.

Based on his results, Terman suggested that gifted children should be identified early, offered tailored instruction, and have access to specially-trained teachers.
What topics is Francis Galton associated with?
Galton was a polymath who made important contributions in many fields of science, including meteorology (the anticyclone and the first popular weather maps), statistics (regression and correlation), psychology (synaesthesia), biology (the nature and mechanism of heredity), and criminology (fingerprints).
What year did Francis Galton contribute to forensics?
In 1823 , another physiologist, Jan Purkinje, noted at least nine different fingerprint patterns. The pioneer in fingerprint identification was Sir Francis Galton, an anthropologist by training, who was the first to show scientifically how fingerprints could be used to identify individuals.
Who was Darwin’s cousin?
Sir Francis Galton , scientist, African Explorer and statistician, was a key figure in statistical history. He was the man who devised the statistical concepts of regression and correlation. He was also Charles Darwin’s cousin.
Who is the father of fingerprint?

What is the IQ of a child whose mental age is equal to the chronological age?
An individual’s mental age is then divided by his chronological age and multiplied by 100, yielding an intelligence quotient (IQ). Thus, a subject whose mental and chronological ages are identical has an IQ of 100, or average intelligence .
