It kind of depends. You can broadly call any kind of search “reasoning”. But search requires 1) enumerating your possible options and 2) assigning some value to those options. Real world problem solving makes both of those extremely difficult.

Unlike in chess, there’s a functionally infinite number of actions you can take in real life. So just argmax over possible actions is going to be hard.

Two, you have to have some value function of how good an action is in order to argmax. But many actions are impossible to know the value of in practice because of hidden information and the chaotic nature of the world (butterfly effect).
