In thinking about or looking for a causality relationship researchers have to decide if they are dealing with a necessary condition. A necessary condition is one that must be satisfied for the statement to be true. Necessary condition is that which must be present for the effect to occur. To put it another way, if B appears then A must have been present. Social sciences seldom deal with necessary conditions, rather they are happy to find sufficient conditions. The concepts of necessary conditions and sufficient conditions help us understand and explain the different kinds of connections between concepts, and how different states of affairs are related to each other.

A sufficient condition is one that, if satisfied, guarantees the statement will be true. Some conditions can be both necessary condition and sufficient condition. Is wage compression a necessary condition for firm-financed general training?

Some examples of necessary condition:

A necessary condition must be there, but it alone does not provide sufficient cause for the occurrence of the event. Only the existence of sufficient grounds can do this.

Being alive is a necessary condition for having a right to life.

Air to breathe is a necessary condition for that human being's being alive.
