Abstract

Eric Cockrell

The purpose of this experiment was to acquire a percentage number for the accuracy of horoscopes. The hypothesis was that most of the subjects that were tested would find that their horoscopes would be at least 50 percent true and that very few, if any of them would find that their horoscopes would consistently be at least 90 percent accurate. Overall, horoscopes were predicted to be at least 40 percent accurate. However, when the names of the signs were switched and the subjects were tested with another horoscope that they believed to be their own, it was predicted that the percentage number derived from that part of the experiment would be higher than the number from when they were tested with their actual horoscope.

In the first part of this experiment, 18 subjects were given the horoscope from the previous day that corresponded with their sign and were asked to tell how many predictions actually came true. In the second part of the experiment, the process was repeated with the exception that the names of the signs were switched around.

The results concluded that most people found their horoscopes to be under 50 percent accurate. Overall, horoscopes proved to be 29.7 percent accurate, which does not support the hypothesis. When the names of the signs were switched, horoscopes were found to be 39.732 percent accurate, which does support the hypothesis. This proves that horoscopes are primarily false.
