The two partners in Human Factors Consultants (HFC) are scientists; we provide expert consultation and testimony to the legal community on the scientific factors that affect the accuracy of eyewitness identifications and fingerprint identifications; the factors that affect the accuracy of memory, child and adult; and the scientific factors that affect the causation of accidents involving human error, design, construction or maintenance issues, and need for warnings. We specialize in reports and testimony that can be understood by non-scientists. Our areas of expertise include

* Eyewitness identification
* Line-up, photo-spread, show-up, and mug-book procedures
* Fingerprint science
* Fingerprint methodology
* Perception
* Memory
* Interview procedures
* Recovered memory
