Research bears this out.
“I’m interested in the boundaries of unconscious processes in the mind,” said Nordgren. “We readily accept that most behavior is driven by mental events that we have no access to. Our heart beats. We pick up a cup or type on a keyboard. All are complicated tasks, but we have no idea how they happen. It takes place in a black box; we have no access to it.”
“But we imagine that those unconscious processes stop at basic behavior,” he continued, “that more complex, higher-order processes are surely driven by our conscious selves. Whether to marry, what job to take, are these the products of conscious machinations of the mind, or processes that we have no access to? It doesn’t need to be a pure dichotomy. But dominant thinking hasn’t been open to this idea.”
