Well, someone searched for this and ended up on this site last month... so its time to analyse this topic.

I think there are 2 angles on this. The first is evolutionary biology and the second being social conditioning.

As we know, the loss of pigment is useful in low sunlight environments (e.g. Northern Europe) and it’s the same pigments (I believe) that is responsible for determining hair colouring.

Without getting into too many tangential theories it pretty much seems that males have preferred blondness (As you might have noticed it seems to be correlated with youth - You develop hair pigment as you get older - although there is the argument relating to child survival when the father is not the legitimate one). We also see the higher female ratio to males in Eastern Europe which has further placed selective pressures.

Anyway, there is a preference for blondes. Like it or not, they have more fun and it’s widely known.

Then we have social conditioning.

If blondes are more highly sought after by males then it is more than plausible that 1) They will be asked out more (developing more outgoing skills) and 2) Not have to work as hard if they want to allow all the nest building males to run around being protector providers.

So, what is probably the most likely typing for a blonde (female)?

Well, simply by the statistics she is more likely to be an F. Probably more likely to be an E (A function of the available lifestyle) and probably more P (As she can get away with it). S is more common than N so S it is.

Hence, most likely to be ESFP. Obviously there are going to be many many differences to this. But this is just a statistical exercise.

One thing though, many an NT guy has been completely confused by the blonde. A strange but alluring creature.
