I recommend caution when receiving an invitation from Polar Insight (also dubbed ‘Polar Intelligence’) to complete a survey. When I received one, it ended up in a deceptive change of the terms. The deception emerged after two emails exchanged with the company’s managing director, James Tattersfield, and an employee.
The case began when the managing director invited me to complete two tasks in exchange for a $125 USD voucher. The two tasks were a survey (‘short form’, in the director’s words) and an hour-long interview.
