BrainHex player typology test

Today I've taken the BrainHex player typology test. Interestingly enough it was difficult for me to point three games that would represent my interests. I easily picked Jones in the Fast Lane, but after some thoughts on StarCraft, Pizza Tycoon, Syndicate, World of Goo and War Inc, I picked SimCity and Fallout. The last appeared indicative to my group. Not sure about the others, but they definitely have strong emphasis on simulation. So here are my scores:

Mastermind: 18
Socialiser: 14
Achiever: 11
Conqueror: 10
Seeker: 8
Survivor: 5
Daredevil: 4

The results are not surprising at all.
Still, I am not sure of the quality of the questionnaire and classification, but I have to admit that it is because I am completely inexperienced with the construction of such tests. To put it straight, I'll come back to the classical question: "Are people objective when they answer questions?" An answer could be that only experiments could tell the actual truth.
