Broken window theory

As I've been really having long working days and hours juggling 2 jobs, I've not been able to stay awake reading my books and sorts for quite a while. However on reading the tipping point, it managed to captivate my attention and I was able to read on.

The book is highly insightful and interesting. One of the theories it put to explain for high-crime rate was that the streets was highly defaced. Crimes are different from intentions. Intentions are easy while crimes take quite abit of commitment to actually do it. The doer would also put himself into a personal peril. So why was crime rate that high?

The proposed theory was a broken window theory where "a house with a single broken window would have a higher chance of getting vandalised and having another window broken than a house which looks new".

The crime rate was solved not by hard handled measures nor employing more enforcers. It was solved by making sure that the "broken window" was immediately fixed. The floors were ensured to be tidy, vandalism cleared, and order restored to the smallest detail. In addition, small crimes were no longer ignored and was given heavier penalty. The result was fantastic.

It somehow seems to also explain alot of human to human interactions and behaviour.
Why would a wedding dinner always start late?
Why would a friend be consistently late for an outing together?
Why would a class skip lessons of a teacher together despite possible punishment?
