The Irrational is one of the few new scripted series coming to NBC's 2023 fall lineup this TV season. This cerebral police procedural with a twist is a welcome addition to the schedule, offering a refreshing take on the police consultant trope. It's based on the book Predictably Irrational by Dan Ariely.
The show features Jesse L. Martin as Professor Alec Mercer, a leading behavioral science specialist who offers his perspective on cases and investigations of all kinds, including cases that go as high as governmental levels and within law enforcement. Mercer's specialty is diving into the nature of rationality and decision-making, and how preconceived notions can impact how we shape the decisions we make.
Since NBC had to push the Law & Order and FBI series to the spring as a result of the writers and actors strike, The Irrational is a great way to fill the gap as a show that was planned for midseason but moved up to the fall schedule.
The Irrational was so well received that it earned a second season pickup at the end of November, paving the way for more stories to come in the future.
What to Watch had a chance to review the new series, calling it "sexy" and "compelling."
Here's everything we know about The Irrational.
