According to an article called "Where did my IQ points Go? in Psychology Today, when we get angry the light goes out in the prefrontal cortex, which is the excutive functioning and decision making region of the brain. It's like we're operating with 10 to 15 less IQ points when we're angry.
Micronutrients and vitamin deficiencies. Micronutrient deficiencies (e.g. in iodine and iron) influence the development of intelligence and remain a problem in the developing world. For example, iodine deficiency causes a fall, on average, of 12 IQ points.
You're stressed out.
"High stress levels are not only associated with poorer brain functioning but may even link to an increased risk of Alzheimer's disease," says Brendan Kelley, MD, neurologist at The Ohio State University Wexner Medical Center in Columbus, Ohio.
Studies using previous versions of the WAIS found that psychiatric patients had lower IQ scores than normative samples, with depression most strongly correlated with deficits in working memory, processing speed skills (Boone, 1992; Micco et al., 2009; Stordal et Page 15 10 al., 2004), and nonverbal reasoning skills ( ...
The brain needs 30 milliseconds for the brain to consciously pick it up. So that unconscious fear and anxiety residing in the amygdala can be blocking critical IQ and decision making resources without you knowing it.

There were significant differences in the impact of childhood trauma on IQ across the 3 groups. Exposure in HCS was associated with a nearly 5-point reduction in IQ (−4.85; 95% confidence interval [CI]: −7.98 to −1.73, P = . 002), a lesser reduction in siblings (−2.58; 95% CI: −4.69 to −0.46, P = .
Aron discovered that many gifted individuals are very sensitive. Therefore they are very creative, but because impressions and emotions come in strongly, they do not always know how to use that creativity.
Intelligence is also strongly influenced by the environment. During a child's development, factors that contribute to intelligence include their home environment and parenting, education and availability of learning resources, and healthcare and nutrition.
Smart people think really quickly, which can make them impatient. They like to get several things going at once so that there isn't any downtime. They think so quickly that, when they multitask, it feels like it's working and they're getting more done, but Stanford research shows that this isn't the case.
Science supports laziness
The data found that those with a high IQ got bored less easily, leading them to be less active and spend more time engaged in thought.
There are many possible reasons why. People with higher IQs often have an increased sense of awareness, deeper levels of empathy, or a fear of failure — all may result in more worry and stress. But anxiety isn't always an obstacle, and it can offer many benefits.
Crystallized intelligence "averages 98 at ages 20–24, rises to 101 by ages 35–44, before declining to 100 (ages 45–54), then 98 (55–64), then 96 (65–69), then 93 (70–74), and 88 (75+)," says Kaufman. Fluid intelligence drops much more quickly.
Many habits contribute to poor brain health, but four areas can have the most influence. They are too much sitting, lack of socializing, inadequate sleep, and chronic stress.
Difficulties talking or talking late. Having problems remembering things. Inability to connect actions with consequences. Difficulty with problem-solving or logical thinking.
Early twin studies of adult individuals have found a heritability of IQ between 57% and 73%, with some recent studies showing heritability for IQ as high as 80%. IQ goes from being weakly correlated with genetics for children, to being strongly correlated with genetics for late teens and adults.
Thus, on average, a bigger brain is associated with somewhat higher intelligence. Whether a big brain causes high intelligence or, more likely, whether both are caused by other factors remains unknown.
Research has shown that there is a high correlation between being intelligent and socially anxious. The higher your IQ, the higher the chance your social apprehension is higher than usual. Of course, that doesn't mean that your social anxiety should be classified as a disorder.
Studies have also found that higher IQ is associated with more mental illness, including depression, anxiety, and bipolar disorder.
Persons who developed PTSD following either assaultive violence or other event type had lower IQ scores at age 6 than those who did not develop PTSD, according to these results.
Having a bad memory is a sign of high intelligence. If you have a hard time remembering, it's a good indication that your brain is more focused on the essential things. Packing your brain full of memories for an exam or a business meeting is overrated and could harm your chances of success.
