1. Ekman declined to release his data for peer review.

2. Charles Honts PhD at the University of Utah attempted to replicate Ekman's findings. It didn't work.

Ekman's research was undisputed until Lisa Feldman Barrett PhD at Northeastern showed Ekman's design. He asked subjects to select from six discrete emotions. When subjects were asked to identify emotions without discrete categories, they were inconsistent.

Ekman argued that he couldn't share his findings because his research could fall into the hands of foreign powers.

We need science. That means robust study design, data, peer review, and replicated results.
