Why do Japanese people like /
judging personality /
by blood type? /
There are two possible reasons /
for this. /
One reason is /
the distribution of blood types /
in Japan. /
Japan has a more even distribution /
of blood types /
than other countries. /
Take a look /
at the data below. /
Each blood type is found /
in a range of 9-38% (percent) /
of the population. /
So, /
it is easy /
to group personalities /
into four groups /
by blood type. /
On the other hand, /
in other countries, /
the distribution of blood types /
is not very even. /
The rates for some blood types /
are very high /
or very low. /
For example, /
in Bolivia, /
93% of people /
have type O blood. /
In such countries, /
it is difficult /
to judge personality /
by blood type. /
