AIR travel is one of the safest modes of transportation, with just one fatal accident for every 16 million flights. There is a good reason for that, says Matthew Syed, the author of Black Box Thinking.

Black boxes in every aircraft record what happens, providing insights during the post-mortem of each air crash so that everyone, from pilots and technical officers to airplane manufacturers, can learn from them.

The same rigour should be applied to investing.
