How to detect BS

I came across a nice article written by Scott Berkun on the topic of detecting BS (bullshit).

He starts with a philosophy of lies... and points out three reasons why people do it:

1) to protect themselves
2) sometimes it works
3) people want to be seen as better than how they see themselves

and then he shares some BS detection tools to help sniff it out:

1) Question: How do you know what you know?
2) Question: What is the counter argument?
3) Time and pressure
4) Never agree to more than your trust allows

Typically if someone ignores these things there's a high chance that BS is present.
