From John Davenport
In discussing the impact of computer algorithms, we run the risk of turning them into scapegoats (7 February, p 30). But all algorithms have their origins in human thoughts and decisions.
In principle it’s a simple four-stage process: define a clear end result; decide on inputs and processes to achieve this end; assemble the appropriate computer language commands; and finally, check and debug.
The first two are under our control, and so it should be possible to make sure that they’re working as intended and make common-sense changes where needed. We’ve all seen examples of user-unfriendly programs which must have been written by the unthinking.
