The Failure of Judgment in Central Banks

In retrospect, it appears like the historically low interest rates we may have had throughout recent times have been a major mistake. These mistakes were made by some of the world's brightest minds. What do you think is the source of this failure of judgment and how can we make sure our institutions get these kinds of decisions right moving forward? I'm a little confused here, Neil. Most people who got a 3% mortgage in 2021 are not complaining about past rates. Just wish I'd locked in for longer.
