BICEPS is a human social behavior model developed by Paloma Medina. Similar to SCARF it applies an evolutionary lens to understanding human social behavior. BICEPS argues that 6 core needs are at the heart of human social behavior. Most behavior is then done in pursuit of those needs, and when threaten a fight-freeze-flight response is triggered.

It can therefore be used in:

• Designing social interactions to minimize threat/triggers
• Managing interaction effectively when they take place. For example, by self-reflection, identification of the “threat”, and choosing response over reaction.
• Reflecting/retrospecting on an interaction to identify what may have led to a sub-optimal outcome.
