Results of Psychology Studies Likely to Fail Replication Test

A new study questions claims made in psychology research after more than half of replicated experiments failed replication testing. Published in the journal Science, 270 researchers attempted to replicate the results of 100 psychology experiments; only 47% of the follow-up studies were able to reproduce the effects of the original studies. About 97% of the original studies showed a statistically significant result, but only 36% of the replication studies showed the same. The strength of the findings of the original studies also appeared to diminish when successfully replicated. Because reproducibility is necessary in science, this calls into question the reliability of the statistics used in the original studies and methodologies in many psychology studies.
