The willingness to offer an extreme guarantee to screen customers and then profit through probability and information asymmetry is a remarkably effective business strategy.
Breaking this down reveals three layers.
The first layer is the screening mechanism. Only people who genuinely need the service and believe in the technology will respond. Hesitant people, sceptics, casual enquirers are automatically filtered out. This is using a promise to screen customers, rather than using advertising to attract everyone.
The second layer is the probability game. Where there is a fifty percent natural probability, serving enough customers means half will succeed. The fees from successful customers cover the refunds for the other half, and the whole enterprise remains profitable. This is not deception. It is the precise application of probability.
The third layer is information asymmetry. Most people do not realise that the outcome is determined by natural probability. They believe it is the result of some special technique. This gap in understanding is itself a business opportunity.
This framework can be applied to many service businesses. Take postgraduate application consulting, for example. Only accept clients whose profiles match the requirements. Use historical data to estimate success probability. Promise a refund if unsuccessful. Of ten clients, seven or eight succeed, and two or three get refunds. The revenue from successful clients covers the refunds with room to spare.
The final lesson is this: use a bold guarantee to screen for the right customers, then rely on probability and information asymmetry to turn a profit. This framework helps to attract customers, control risk, and maintain profitability all at once.
