The Human Factor is a 2022 book written anonymously by Israeli intelligence officer Yossi Sariel, head of Unit 8200, under the pseudonym 'Brigadier General B.'. It explores human decision-making and leadership in intelligence and military contexts, examining the human elements influencing decision-making, leadership, and errors in military and intelligence operations, drawing on real-world examples from Israeli intelligence activities. The book became highly controversial for allegedly disclosing classified details about operations, including the 2008 assassination of Hezbollah commander Imad Mughniyeh and other sensitive missions, prompting a police investigation into Sariel for potential breaches of confidentiality and leading to debates on the ethics of anonymized insider accounts in national security.
