Well, a new study reported in The Economist shows that disorder leads to more disorder and crime.
AHI reports on the story and it is fascinating.
When the researchers had graffiti on the nearby wall, petty crime and littering increased dramatically. I suspect this study can also be applied to homeschooling. Although you can be too over the top in having a spotless home, an organised home is much more efficient for work, study and play. At last you can find your things easier!
