How Flexible Is Your Thinking Today?
Dr. Dooriddle’s Creative Reasoning Test
Form C: The Crazy Relatives

Most tests measure what you know.
This one measures something different:
your ability to make connections
your flexibility of thought
your power to generate possibilities
your skill at seeing relationships others miss
In school, many questions have one correct answer.
In life, many problems do not.
That is why creative reasoning matters.
In a world where facts are easy to retrieve, flexible thinking is more valuable than ever.

Important Note
This is not an IQ test and not a measure of permanent ability.
It is a snapshot of one important set of trainable thinking skills.
Like muscles, these abilities can improve with use.

How This Test Works
Each puzzle gives three clue words.
Your task is to think of a fourth word related to all three.
Connections may involve:
similar meaning
opposites
sound-alikes (homophones)
combined words
common phrases
imaginative associations
Sometimes more than one answer may work.
If you honestly like your answer better than mine, go with it.
