Like scientists,all of us construct theories,which Kelly called

A) emotional and illogical assumptions.
B) scientific comparisons of data.
C) personal constructs.
D) insights from our unconscious.

According to Kelly, each individual constructs personal constructs or ways of defining and organizing their experiences. This is in contrast to emotional and illogical assumptions or insights from the unconscious, which are not necessarily based on conscious thought and reflection. While scientific comparisons of data may involve the construction of theories, this is not the specific construct Kelly referred to.
