Textbook Problem

Once there was a highly intelligent turkey that had nothing to do but reflect on the world's regularities. Morning always started out with the sky turning light followed by the master's footsteps, which were always followed by the appearance of food. Other things varied, but food always followed footsteps. The sequence of events was so predictable that it eventually became the basis of the turkey's theory about the goodness of the world. One morning, after more than 100 confirmations of this theory, the turkey listened for the master's footsteps, heard them, and had its head chopped off. Any scientific theory is modified or discarded upon discovery of contradictory evidence. The absence of absolute certainty has led some people to conclude that "theories are irrelevant because they can change." If that is so, should we stop doing scientific research? Why or why not?

Summary Introduction

To explain: How the turkey’s theory regarding the “goodness of world” was changed and explains the reason for the change of scientific theories.

Concept introduction:

Scientific theories are unfalsifiable hypothesis that even after many years of rigorous testing is helpful for making predictions about a wide range of phenomenon. Scientific theories may be revised upon the discovery of new data. Scientific theory is consistent with the existing evidence, and scientists use it to make successful predictions about a wide range of other phenomenon.
