Imagine a world where the decision of whether you will get the mortgage for your first house will be determined according to how often you talk to your mother or what route you take to get to work? It seems a far-fetched idea, but, to some extent, it is already happening. Dr Manju Puri, Professor of Finance at Duke University, acknowledged that banks could use a person's phone usage data to decide whether that person will get a loan. According to Dr Puri, people who call their mother every day or choose the same route to work are less likely to default. "We know what's statistically correct to do and what's morally correct to do are often two different things," Aidan Connolly, CEO of Idiro Analytics, has acknowledged.
