This article makes a case for the transformative integration of psychological jurisprudence and neuroscience by emphasizing the importance of psychological accounts that recognize human agency and belief in free will, provided they support justice, dignity, and responsibility. It highlighted the distinction between perspectives that essentialize human nature and those that appropriate agency as a continuous process. Rather than treating determinism and free will as mutually exclusive, the article argues for a compatibilist framework that balances both. Through a critical analysis of compatibilism, it advances a psychology of the self as an ongoing process, offering a critical response to neuroscientific determinism without reducing human agency to passivity.
