About lies

I really don't know what I should write about in my blogs, so I'm gonna just talk about me researches that I was doing lately.
Actually, I'm interested in human psychology, so lying topic really did catch my attention. Right now I'm doing a summary of articles about why people tend to lie, that I've read. Probably gonna post it here, once I'm done. If someone is interested, I'd like to hear your opinion on why some people start to lie constantly while or after stressful situations.
