Engineers vs. Technicians

The difference between engineers and technicians An engineer is given a system which does not work.  The engineer inspects the system and discovers a component installed upside down.
The engineer thinks,  "this component has been installed upside down.  I don't know why it is upside down , but the person who installed it obviously had a good reason for installing it this way.  I will not tamper with it."
A technician is given a system which does not work.  The technician inspects the system and discovers a component installed upside down.
The technician thinks, "this component is upside down.  It should be installed right way up".  The technician takes out a screwdriver and reinstalls the component.
The engineer is an intelligent person. All the engineer's  friends are intelligent people.  It would never occur to the engineer that the reason the component was installed upside down is that the person who installed it is a freakin' idiot.
