Question

according to the experts, why is it harder to quit a bad habit than to start a new one?
the habit system in the brain runs on autopilot
people dont care enough to stop
goals and habits are controlled by the same brain system
bad habits require more motivation

Explanation:

Neurological and behavioral science research shows that once habits are formed, the brain's habit system operates automatically (on autopilot), bypassing conscious decision-making. This automaticity makes interrupting ingrained bad habits far harder than initiating a new, unestablished behavior which doesn't have this deeply wired automatic brain pathway. The other options are incorrect: people often care about stopping bad habits, goals/habits use different brain systems, and bad habits do not require more motivation but instead need to override automatic brain responses.

The habit system in the brain runs on autopilot
