Laetus
Laetus
Laetus conducts long-term research into probability, behavioural patterns, decision-making under uncertainty, and the concept of personal luck. Each experiment contributes new data to an expanding public research project.
Experiment #2 has now been successfully completed. Both public Laetus experiments are now archived and together form the first long-term behavioural dataset collected by the project.
The next experiment will build upon these findings with expanded methodology, larger datasets and additional behavioural metrics.
The completed experiments explore possible relationships between Luck Index, behavioural patterns, decision timing, and long-term statistical outcomes observed across multiple international lottery systems.
Users generate virtual lottery combinations inside Laetus.
The platform evaluates behavioural patterns and continuously updates each user's Luck Index.
Anonymous statistical data is accumulated and analysed across many rounds.
Selected combinations may be tested independently in real-world lottery systems.
All experimental outcomes, statistics and rewards are published openly.

Rather than evaluating individual lottery outcomes, Laetus aims to build one of the world's largest longitudinal datasets focused on probability, behavioural decision-making and the measurable properties of personal luck.
Each completed experiment strengthens the empirical foundation of the project while improving future analytical models.
The long-term objective is not to predict lottery results, but to better understand how human behaviour interacts with uncertainty over extended periods of observation.
Can personal luck be measured?
