Calling the run method does not start a new thread. When you call start on a Thread object, the JVM starts a physical thread on the OS and then calls run. So if you call run directly, you are just using the calling thread, not creating a new thread.

Any intelligent fool can make things bigger, more complex, and more violent. It takes a touch of genius - and a lot of courage - to move in the opposite direction. - Ernst F. Schumacher
It is sorta covered in the JavaRanch Style Guide.
