Interestingly i took my first test back in 06 in school (those with a score greater than 5 in any direction were asked to stand - i was the only one on the right, the others were commies) and got +7, +3.. over time i mainly became more socially liberal and through my economics degree a little more open to new ideas i think and so had +5, -2 however i have then got +8, -2 and +6, +3.
Essentially you can draw a box for myself in which i shift around 5-8 on the economic scale and 3-(-)2 on the social.
