Almost everyone wants to get smarter. We struggle to improve our
16_ , intelligence and attention. We drink cup after cup of coffee to help us
17_ the day.
18 __, a new study published in
Current Directions in Psychological Science warns that there are
19___ to how smart humans can get.
Each of our body parts develops in a certain way for a reason.
20 _, we are not 3 meters tall
21 _ most people’s hearts are not strong enough to send
22 _ up that high. Scientists say that our thinking ability works in the same way. A baby’s brain size is limited by a series of __
23 , such as the size of the mother’s pelvis (骨盆). If our brains developed to be bigger, there could be more
24 during childbirth.
The study of Jews, who have an average IQ much _
25_ than other Europeans, showed they were more
_26_ to develop diseases of the
_27_ system. This might be because of their increased brainpower.
If intelligence cannot be improved, can we at least get better at _
28 _ ? Not really, say scientists. They studied
_29_ like caffeine (咖啡因)that improve attention. They found the drugs only helped people with serious
30 _ problems. For those who did not have trouble paying attention, the drugs could have the
31 _ effect. Scientists say that this suggests there is a(n)
32 limit to how much people can or should concentrate.
Our memory is also a “double-edged sword”. People with extremely good memories could
33__ having a difficult life because they cannot
_34 bad things that happen to them.
Thomas Hills, one of the authors of the paper, said that
35 all the problems in trying to get smarter, it’s unlikely that there will ever be a “super mind”.
