Approach and avoidance motivation (BIS/BAS)
Two basic motivational systems: one moves people towards rewards (approach, BAS) and one makes them halt and scan when a goal might bring punishment or conflict (avoidance, BIS). People differ in the sensitivity of each.
What drives it
It explains why one person sees a new opportunity and leans in while another sees the same opportunity and lists what could go wrong. For identification, it tells you whether to frame a request around gains or around safety.
How it shows
Work
High BAS: first to volunteer, energised by targets and bonuses, talks about upside, under-weighs risk, gets bored in maintenance roles. High BIS: asks 'what's the downside?', reviews contracts twice, slows down when uncertain, performs well where errors are costly and badly where boldness is needed. Avoidance goals sound like 'I just don't want to look stupid in the board meeting'.
Relationships
An approach-driven partner plans adventures and initiates; an avoidance-driven partner focuses on not upsetting things, which can look like passivity. Conflicts arise when one wants to try and the other wants to be sure.
Self
Notice whether you describe your goals as getting something or not losing something. Avoidance goals are more tiring and less satisfying even when met: relief rather than pleasure.
What tells it apart
Regulatory focus (promotion and prevention): Regulatory focus is about the type of goal (ideals versus duties) and the strategy used; a prevention-focused person can still pursue a goal eagerly once it is framed as a duty, whereas a high-BIS person freezes under conflict whatever the goal.
Behavioural inhibition: Behavioural inhibition is a childhood temperament shown as shyness and wariness with novelty; BIS sensitivity is a broader adult tendency to pause under goal conflict and can sit in an outgoing person.
Neuroticism: Neuroticism covers chronic negative emotion of all kinds; BIS is specifically the brake that engages under uncertainty. Watch for someone calm in general who stops sharply at ambiguous risks.
A test
Present the same proposal framed as gain and then as loss avoidance, and see which frame gets movement.
Questions to carry
- Framed as a gain and then as a loss avoided, which version of the same proposal got movement?
- Faced with a new opportunity, what do I notice first, what I could get or what could go wrong?
How strong the research is
moderate. The broad approach and avoidance distinction is robust across psychology; Gray's specific systems were revised in 2000 and their mapping to traits and brain circuits is still debated.
