Before defining antipatterns, we must define a pattern. A pattern is a method of solving a common problem by using a generalized procedure1. Therefore an antipattern is a solution that presents more problems then it addresses2.
Initially, the term antipattern was coined in engineering and software development, but its definition can be used in a much broader sense too. There is already a wide range of resources and literature on antipatterns in engineering and software development. I want to refer the interested reader to Wikipedia and the extensive collection of antipatterns on the c2.com wiki.
After the horrible attacks on the WTC many people decided to take their car instead of a plane. However, this is actually even more dangerous.
