Behavioural economics helps B2B product teams understand how people make choices and how design choices can influence outcomes.Bounded rationality explains that people often choose what feels acceptable or 'good enough' based on limited time and information.In a B2B context, users tend to default to familiar plans, obvious settings, or the quickest way to complete a task.Buyers often focus on the price in relation to their budget and frequently opt for the middle option due to the compromise effect and price anchoring.
