Mind Control

In the 1980s, Princeton University conducted a large-scale experiment to test if humans could influence machines with their minds. Led by Doctor Robert John, the study involved two and a half million trials over 12 years. The results suggested a minor effect, but it was not statistically significant. Despite the large sample size, the findings were not considered significant by the scientific community. Other universities replicated the study on a smaller scale and found no significant results, highlighting that a larger sample size does not necessarily imply greater significance.

What was the primary goal of the Princeton University experiment conducted in the 1980s?

• To improve random number generation

• To develop new electronic devices

• To study the effects of meditation on brain activity

• To test if humans can control machines with their minds

What was the main challenge Doctor Robert John faced regarding the experiment's results?

• Lack of funding for further research

• Difficulty in convincing peers of the results' significance

• Inability to publish the findings

• Technical issues with the random number generator

How did the scale of the effect observed in the Princeton experiment compare to typical statistical significance?

• It was much larger than typical significance

• It was slightly larger than typical significance

• It was much smaller than typical significance

• It was exactly the same as typical significance

What does the Princeton trial suggest about the relationship between sample size and statistical significance?

• A larger sample size does not necessarily mean greater significance

• Smaller sample sizes are more reliable

• Sample size has no impact on statistical significance

• Larger sample sizes always lead to more significant results

What was the outcome when other universities attempted to replicate the Princeton experiment on a smaller scale?

• They found completely opposite results

• They found the same results as Princeton

• They found no significant results

• They found even more significant results
