A modular, electronic lie and emotion detection system is disclosed. The modular, electronic lie and emotion detection system can include a computing unit programmed for multifactor dimensionality reduction, anomaly detection, and prediction of lies and emotions and may also be configured to communicate with the modular and/or remote unit(s) via an interface or port or connector to which the computing unit and the modular and/or remote unit(s) are coupled. The modular and/or remote unit(s) can supplement the functionality of the computing unit.
