Kaspersky Lab and Mensa are inviting Internet users to a very special challenge over the summer. TheGlobal Think Test is made up of a series of online brain games and meant to challenge the combination and calculation skills of participants. On the ‘Global Think Test Day’ on September 6, 2014, a global competition will be held. Those demonstrating the best combination skills can win US $25,000. The organizations are trying to make people aware of the fact that sanity and reason are still the best weapons against many cyberthreats. But, as humans, our behavior is often geared towards being social and shaped by limited cognitive resources, say psychologists. So we need to train our alertness.
