Hanlon's razor corollary

Hanlon's razor, a corollary of Finagle's law, is an adage which reads:
“
Never attribute to malice that which can be adequately explained by stupidity.
”
Also worded as:
“
Never assume malice when stupidity will suffice.
”
Hanlon's Razor is a favorite of hackers and often shows up in sig blocks, fortune files, and the login banners of BBS systems and commercial networks.
