# Thread: 5 introverts in immediate family ... what would be the probability?

1. ## 5 introverts in immediate family ... what would be the probability?

My parents, two brothers & myself ... all I's. Yep, 5 of us.

How improbable is that?

2. Oh just realized if I posted this in the NT section, they would figure it out for me LOL!

3. Our family of five has four introverts... plus one ESFP.

...Poor guy.

4. Someone called?

Introverts are around 25% of the population. Assuming that your individual types don't have anything to do with each other (that is, types aren't genetic)..

.25*.25*.25*25*.25 = 0.09765625%.

.. I think.

But yeah, I figured I'd cover the numerical answer if that's what you're looking for

5. Jennifer - LOL, I was just thinking about that too ... if there was one of us an E. Pour soul!

And I'm the most outgoing one LOL; family get-togethers are generally ... quiet!

if the odds of being intro/extro are 50/50 and the draw is random, then the odds would be 1 / 2 x 2 x 2 x 2 x 2 = 1/32.

But we're talking genetics. I don't know if it's random.

And I'm not sure if that 75/25 number is correct, greed -- it seems like bs to me. I seem to run into a lot more introverts than extro, to be honest.

7. Yes, I have seen the estimated proportion of E-I vary from a 75-25 ratio to 50-50.

Impressive result either way!

.03 (Jennifer) vs .09 (greed) ...wait a minute, something is wrong!

(Who wants to win points and guess what it is!!!)

What the hay, let's round up & say it's around 1% ... that's still pretty improbable!

8. I thought the spread for intro/extraversion was 50-50. In other words:

Extraverts = 50% of population
Introverts = 50% of population

I come across far more introverts than extraverts in my daily life.

And I run into more extroverts.. I guess it probably depends on what environments you frequent most The type and preference percentages by population changes way too drastically based upon which source you're looking at, especially the T/F dichotomy. You'd think that there'd be an easy way to get that information, at least for those who've taken the official test..

Whatever the correct percentage i is, it'll be i^5. So...we'll say less than 5%, in any case.

If genetics does play a role, which I'm sure it does, maybe closer to 5-15%.

You mean .03 versus .0009, or 3% versus .09%. Decimals aren't the same as fractions.

How many points do I get?
