What is Behavioral Analysis?

Behavioral analysis is the detailed examination of an individual’s behavior to assess their personality.  This is based on the foundational principles that our behavior reflects our personality and the best predictor of our future behavior is our past behavior.  

The American Psychological Association defines personality as “... individual differences in characteristic patterns of thinking, feeling and behaving.” Our personality is reflected in our decisions and actions, particularly in our interaction with others. Therefore, analysis of an individual’s past behavior results in a personality assessment which is the foundation for strategies to manage critical situations. 

The methodology utilized by MacKizer Behavioral Analysis Consulting is based on the FBI Model of criminal investigative analysis which was formulated in the 1970’s. Over the years, criminal investigative analysis evolved to encompass not only personality assessments to aid in criminal investigations, but also to aid in counter terrorism and threat assessments. Today, the FBI’s Behavioral Analysis Unit consists of four operational units:

  • Behavioral Analysis Unit 1 (counterterrorism and threats)

  • Behavioral Analysis Unit 2 (cyber crime)

  • Behavioral Analysis Unit 3 (crimes against children)

  • Behavioral Analysis Unit 4 (crimes against adults)

Since this process has evolved to address critical situations beyond criminal matters, it is more aptly named behavioral analysis. MacKizer Behavioral Analysis Consulting utilizes this process to provide decision makers with strategies to effectively manage areas such as 

  • insider threats of violence or theft of propriety information

  • external threats of violence 

  • risk of sex offending

  • threats of damage to an organization’s reputation

  • cold case homicides



Mark founded MacKizer Behavioral Analysis Consulting after retiring from a 27-year career as a Special Agent with the Federal Bureau of Investigation (FBI).  He spent most of his career conducting homicide, child abduction, and drug trafficking investigations. The last 7 years of his career he was a Supervisory Special Agent assigned to Behavioral Analysis Unit 3 (BAU-3) at Quantico, Virginia.  While at BAU, he was responsible for providing behaviorally-based operational support and training to federal, state, local and international law enforcement agencies involved in the investigation of child abductions, mysterious disappearances of children, child homicide and child sexual victimization. The operational support involved the behavioral analysis of violent offenders to produce products related to risk, personality and threat assessment.
