Argumentative Essay On Intelligence

Intelligence is a function of how well the brain works, and it's well established that our brains are designed by genes so it's not entirely surprising that some deem this as proof that our genes play a part in deciding a person’s intelligence. However, this is not a widely accepted fact and many scholars would argue intelligence is indeed not fixed by ones genes but instead manipulated by other factors.

Sir Francis (Galton, 1869) believed intelligence was inherited, and saw conceptualised general mental ability as a largely inheritable trait, and very much like physical traits, having a normal distribution in the population. Biologically, siblings share genes, and evidence shows that (Schacter, Gilbert & Wegner, 2012) intelligence test scores of siblings to be much more similar than the intelligence scores of unrelated people. Identical twins(monozygotic) share 100% DNA and studies show …show more content…

Recent information collected showing an increase to our IQs have many asking the question, are we smarting than our ancestors? Unlike our predecessors, we live in a time that poses a greater range of cognitive problems than our ancestors encountered, and as a result we've developed new cognitive skills and the kinds of brains that can deal with these problems. So in a way we are getting smarter throughout history, though it is widely debated if this is due to our environment or genes. Since IQ tests have been standardised many times over the last one hundred years, scientists have participants take a test designed for a previous age and record the results. What (Flynn, 1994) unearthed was that new test takers score much higher than those of the older generation. Flynn and his colleagues guessed that the difference in scores was due to improving modern environments. To them IQ is part heritable and part environmental- provide a child with opportunities to learn and they're likely to have a higher IQ later in
