A switch you can flip.
That you can change your attitude sounds simple, but when examined carefully it becomes unclear what mechanism would allow that to happen directly. People often talk as if attitude were a switch you can flip. In reality, attitudes emerge from underlying processes which consists of biology, learning history, current conditions, incentives, and cognitive models. You do not step outside those processes and select from a menu.
Organisms act according to pressures and constraints. Sometimes the output looks like emotional reaction, sometimes like calculated cooperation. Both are strategies that the system has available. The moment-to-moment selection among them is not a free command issued by a detached “self.” It is the result of competing processes inside the organism.
This idea fits well with the deterministic perspective already present in Baruch Spinoza. For him, the feeling that we freely decide comes from ignorance of the causes shaping our actions. We experience the outcome of a process and then assume we authored it. But if you trace the chain of causes back to physiology, past events, environmental triggers the action follows necessarily from those conditions.
Now what about attitude? The is no free will. While you cannot usually change it instantly by command, there is still a weaker but real mechanism for modification. Humans can change inputs into the organism, for example, what they pay attention to, what environment they stay in, what information they expose themselves to, and how they interpret events over time. Those changes slowly alter the probabilities of certain responses. So attitude shifts are typically indirect and gradual, not voluntary flips. Structurally, what actually changes attitudes are altered conditions, repeated feedback, and updated models in the brain.
The insight about instinct versus rational cooperation is important, though. Humans carry both systems because different situations require different responses. Rage can be adaptive in immediate threat contexts. Cooperation becomes more effective in stable social environments. Neither is “chosen” in the sense of pure freedom; both are outputs from the system given the current configuration of pressures.
People do not freely choose their attitude in the way motivational language suggests. But attitudes can still change because the system itself is plastic and responsive to inputs over time. What people call “deciding to change” is usually the moment when the underlying system has already shifted enough to produce a different response.
