    Memoirs of extraordinary popular delusions and the madness of crowds

    Charles Mackay · 2009

    First published in 1841, this history chronicles the popular foolishness of Mackay's day.

The author discusses and usually debunks a wide variety of subjects and events. These include economic bubbles like the tulip craze of Holland in 1637 or the Mississippi Company financial bubble of 1719; alchemy, which was of particular interest to individuals who wanted to create gold out of lesser-valued materials; the Crusades, also known as the Middle Ages mania; witch hunts, the persecution of thousands of innocent victims that arose from either supernatural ill fortune or neighbors with a score to settle; duels; the political and religious influence on beards; and several others. This work, with all of its interesting observations, is an entertaining and insightful book that explores the phenomenon of crowd mentalit

      For the tulip mania, as well as other manias, I very strongly recommend: "Memoirs of Extraordinary Popular Delusions and the Madness of Crowds" by Charles Mackay[1]

      Very informative and a very enjoyable read.

      The artifacts are usually beautiful from good Workmanship Standards, Design For Manufacturability, and systematic Metrology. Dragging us all into the future one project at a time.

      Note that training an ML model with such data would be pointless, as statistical saliency forms a paradox with consumer product design compromises. Note, there are _always_ tradeoffs in every problem domain.

      My first encounter with John Law's story was after reading Charles Mackay's 1852 "Memoirs of Extraordinary Popular Delusions and the Madness of Crowds".

      It's plainly told and unsurprisingly familiar if you've followed the causes of any of the negligence entertained by the SEC this millennium.
