Same data, opposite results. Can we trust research?
The reliability of research is called into question, after an experiment shows that results can have as much to do with the analysis of the data, as the data itself.
When Professor Martin Schweinsberg found that he was consistently reaching different conclusions to his peers, even with the same data, he wondered if he was incompetent. So he set up an experiment.
What he found out emphasises the importance of the analyst, but calls into question the level of trust we can put into research.
