A sane judgement requires a careful distinction between two kind of ideas that we have on the external world. They are named observations and inferences.

Observations result from personal perception. To observe something, we must see, hear, feel, taste. The inferences are decisions on the meanings of our observations.

These two types of ideas are essential to our own functionning, but when we confuse inferences and observations, we have some troubles.

Carefully read the following story, assuming that all it says is accurate. But, at times, they are deliberately vague. Do not try to memorise it, since you may refer back to the story whenever you wish.

To simplify that test, we consider that all what the characters claim to have observed is also accurate.

Read then the numbered statements and decide if each one of them is true, false or doubtful to you. Clicking the "T" means that you are sure that the statement is definitely true. Clicking the "F", means you are sure that it is definitely false. Clicking the "?", that you cannot decide whether it is true or false. If any part of the statement is doubtful, click the "?".

Answer each statement, without going back to change a preceding answer. Do not re-read the assertions after having answered. These changes or second readings would alter the results of this test.

If you mail your answers, a correction will be returned to you. Only the final result will appear, expressed as a percentage number of correct answers.
