choicehave

choicehave is a decision‑support platform that assists users in making informed choices across a wide range of personal and professional contexts. Developed by a consortium of behavioural scientists, data engineers, and user‑experience designers, the service launched publicly in 2019. It employs a hybrid model that combines evidence‑based heuristics with machine‑learning algorithms to generate personalised recommendations.

The system is organized around three core components: an input module that gathers relevant data through structured questionnaires or API integrations, a reasoning engine that applies principles from behavioural economics and cognitive psychology, and an output interface that presents actionable options ranked by factors such as likelihood, risk and user preferences. Users can customise criteria weights via an intuitive dashboard, and the platform supports both single‑use decisions and ongoing decision‑tracking.

choicehave has been adopted by a range of organisations, including non‑profit charities, educational institutions and small‑to‑mid‑size businesses, to improve decision quality and reduce cognitive load. In academic settings, the platform has been used as a teaching aid in courses on decision theory and data ethics. Critics have raised concerns about data privacy, though choicehave claims compliance with GDPR and industry best practices. Evaluations published in the Journal of Decision Systems have reported a statistically significant improvement in decision satisfaction among users over a six‑month period.
