This week I conducted a survey asking respondents to report their Myers-Briggs personality type and Hogwarts house. 115 people took the survey, producing 112 valid data points (each consisting of one response for type and one response for house). The raw data is here.

Since the number of respondents from each house was unequal, I'll be speaking in terms of more or fewer house members scoring each type than statistically expected, not straight percentages.

All respondents
Gryffindor 15.2%
Hufflepuff 10.7%
Ravenclaw 53.6%
Slytherin 20.5%

SJ (Guardian) 8% of the whole
Gryffindor 0
Hufflepuff 22.2% (of this temperament)
Ravenclaw 33.3 %
Slytherin 44.4%

SP (Artisan) 3.6% of the whole
Gryffindor 50% (of this temperament)
Hufflepuff 0
Ravenclaw 25%
Slytherin 25%

Data for the Guardian and Artisan temperaments was too slight to be conclusive.

NT (Rational) 53.6% of the whole
Gryffindor 13.3% (of this temperament)
Hufflepuff 5%
Ravenclaw 58.3%
Slytherin 23.3%

Half as many H's as expected, slightly fewer G's, a few more R's and S's.

NF (Idealist) 34.8% of the whole
Gryffindor 17.5% (of this temperament)
Hufflepuff 20%
Ravenclaw 52.5%
Slytherin 10%

Half as many S's as expected, twice as many H's, a few more G's, slightly fewer R's.

Given the small numbers, this is relatively close to the expected proportions. It looks like there's a tendency for Hufflepuffs to be NFs, and Slytherins to be NTs, but it's not nearly as strong as I'd have thought. Looked at another way:

Gryffindor 15.2% of the whole
SJ 0
SP 11.8% (of this house)
NF 41.2%
NT 47.1%

Hufflepuff 10.7% of the whole
SJ 2 16.7% (of this house)
SP 0
NF 7 58.3%
NT 3 25%

Ravenclaw 53.6% of the whole
SJ 5% (of this house)
SP 1.7%
NF 35%
NT 58.3%

Slytherin 20.5% of the whole
SJ 17.4% (of this house)
SP 4.3%
NF 17.4%
NT 60.8%

There were also quite a lot of Introverts. All the houses had an Introvert majority, but some were stronger than others.

All respondents
Introvert 85.7%
iNtuitive 88.4%
Thinking 58.9%
Perceiving 60.7%

Introvert-Gryffindor 64.7% (of house)
Introvert-Hufflepuff 91.7%
Introvert-Ravenclaw 90%
Introvert-Slytherin 78.3%

Gryffindor and Slytherin had rather fewer Introverts than statistically expected, Hufflepuff and Ravenclaw slightly more.

What's most remarkable about this survey is the huge percentage of INFs (Introverted Idealists) and INTs (Introverted Rationals), much more than you'd expect to find in a randomly chosen sample of the general population. Is this a tendency of fandomers? HP fandomers? LJers? Hard to say.

A much better way to do this would have been to start with a group equally divided between the four houses and have them all take the MB test. I didn't realize the pool was going to be so heavily skewed toward Ravenclaw.

Thanks to everyone who participated!
