Category - Logical Reasoning

Insurance manager: “Our system estimates a ‘risk rate’ for each car owner based on their driving history. Some may question the ability of a computer system to reliably estimate each driver’s risk of an accident. However, the figures provided by the program are remarkably consistent, so we can be sure the program is reliable.”

The reasoning in the insurance manager’s argument is flawed because
  1. Fails to establish whether reliability or consistency is a more important trait for a computer program.
  2. Regards reliability as the sole criterion for judging the efficacy of a computer program.
  3. Fails to consider that a computer program could produce consistent results without those results being reliable.
  4. Fails to consider that a computer program can never substitute for human knowledge.
  5. Fails to consider that driving history is not an appropriate metric to use to predict a driver’s risk of an accident.
Explanation
Answer: C - The reasoning is flawed because it fails to consider that a computer program could produce consistent results that are not reliable. The manager claims that the program is reliable because the figures are consistent, but consistency does not have to guarantee reliability.
