Something i've been curious of.

[Mike L.]

It's probably known for most people in this group that the jaeggi
study purports to have observed an increase in gF of around 40
percent.

What i believe most people do not yet know is specifically how much,
in IQ points, that amounts to.

I've been wondering: Exactly how many IQ points can one expect to
increase as a result of DNB training AFTER those 19 days mentioned in
the study and what this means for further training (does the slope of
increase remain steep or does it reach a plateau)?

Surely, these things might need some further studying to figure out
but nonetheless, what do you guys think?

[Pontus Granström]

I would say that typically each problem on the BOMAT would represent 3-5 points so everything from 12 to 20 points.

[Mike L.]

in addition to this, how many IQ points would one need to have
increased in order to note a significant improvement in their
cognitive performance over time?

Would, for example, an increase of merely 3-4 IQ points be enough for
one to note an enhanced ability in solving questions of math?

[Pontus Granström]

3-4 points over time would definitly make a diffrence (it has to).

If you want to get an idea of how many points makes a difference,
think of IQ in terms of it's distribution within the population. The
average college graduate has an IQ of 115 so let's pretend that's
you. Statistically, that means only 1 in 6.3 people have an IQ as
high (or higher) than yours. If you think of an average group of 6
people (Americans) and pick the smartest person, you might have an
opinion of how intelligent that person probably is. If you increased
your IQ 3 points you would have an IQ that only 1 in about 9 people
have. Now the smartest person within the group of 9 people is
probably much more intelligent. If you increased your IQ 10 points
(to 125) that is a score only 1 in 21 people get. If you jumped from
a score about 1 in 6 get, to a score 1 in 21 people get that is a
pretty big difference I would say. It's pretty subjective so you have
to think about how much it matters to you, but personally I think
probabilities are a useful way to look at it. Here's a full table of
IQ distribution:

I'm not sure the rarity of IQ is a good way to describe the actual difference in cognition that you might experience with increasingly higher levels. It's non-linear, and I suspect there are quanta in cognitive function.
