The article is good but misses one point...practicality. Anyone to fail pshycometric test is just not good at lying.. I have myself gone thru a couple of them, and it is very clear..to pass this test u need: 1. Be consistent, select same answer 2. For carrying out point 1, always select answer which will show you as a postive , happy living, proactive person. Its just like passing the written test for getting driving licence in US, always select the option which is most safest whether logical or not.
