Black and white thinking isn't very logical to be honest. For every instance of this kind of thinking, you see every event in only one of two ways - either in a 'black' light, as bad, or in 'white' light, as good. All or nothing. For example, the question of human nature - black and white thinking would be to say that a person is either good (white thinking) or evil (black thinking). Logically speaking, it is not probable due to so many little shades of gray and differences between people. People are simply human.
Other example. If you leave bed today, then you're fine. If you don't, you're lazy. However, this thinking process didn't take into account the context of the situation. If you think logically, you may find reasons for staying in the bed - sickness, depression, broken leg. In these instances, does staying in bed really mean you're lazy? No, it means you're ill.
Black and white thinking is, in a way, 'the easy way out'. It accepts 'theories' without even trying to consider 'proof' or 'instances'. It's like a scientist that will consider a theory real without challenging or testing it in any way. It's a distorted way of thinking that would be better to be avoided.
