Why have many psychologists begun to worry that some of the published results may not be replicable?

What will be an ideal response?

Throughout the world, many psychological researchers are conducting studies. Overall, a huge number are conducted. Random fluctuations in the data will occasionally produce an unlikely event, with p < 0.05 . Researchers attempt to publish any result that appears to be statistically significant, and therefore some of the published results (including some that seem very interesting) may be accidents, or may represent a finding that occurs only under limited circumstances.
