The Kelly Grid is a tool for understanding how you think of people. Down the left hand side, write names of people. Pick any three, and think of an attribute which distinguishes one from the other two. Write this attribute at the top of the first column. Pick another group of three, and find an attribute for the second column. Repeat, until you have around six attributes. Then fill in the table, marking each person according to whether they posess this attribute.
|rejecting person||threatening person||best friend|
|successful person||happy person||ethical person|
The chart below plots the people you chose, and draws a line for each attribute. You will probably see that the attributes cluster in groups. This reveals patterns in your thinking—constellations of ideas which you may not be consciously aware of. You will probably see that the people cluster in groups too, sometimes in surprising ways.
To interpret the figure, choose an attribute and look at its line. Rotate your head so the line is horizontal. Each person lies above or below a particular coordinate along the line, and that coordinate indicates how strongly that person possesses the attribute—the extremes of the line indicate Yes and No answers for that attribute. (For some attributes the Yes–No line is very small. This means that the attribute is not well represented the screen: to see it properly you would need three dimensions.)
