  • 1. crises: Terrorism, Global warming, pandemic viruses, recession and global wars
  • Pandemic, Global warming, Global recession, Terrorism and fads (books, music and movies) Index fallen by 29.2 per cent and the odds are 10^50
  • 1. Thought Experiment : Bringing 1000 persons in a room and measuring the heights and wealth and book sales
  • Daniel Kahneman and Amos Tversky from Israel ( Heuristics and Biases – Nobel Prize for Economics in 2002) Confirmation bias : Terrorists and counting sequence (2,4,6..), Global warming and how Pakistanis and Indians read the same news with different perspective Narrative fallacy:1) 13:01 US Treasuries fall; Hussein capture may not curb terrorism and 13:31 US Treasuries rise; Hussein capture boosts allure of risky assets;2) which is more likely –a massive flood somewhere in America or a massive flood in California 3) see in the back page Ludic fallacy: Life is not a game defined rules, players and pay-offs, Dr. John Vs Fat tony & Casino Case study Silent evidence: How to become a millionaire in ten steps. Get the economist article from Predictably irrational
  • Philip Tetlock research- Taken 27,000 predictions from 300 specialists and asked to predict events in political, economic and military events Empirical tests shown that we are bad at guessing as our error rate is 15% to 30% Take example of IIM grad Vs Avenue Rd. babu and get the example of Mona Lisa painting valuation
  • Sherwin Rosen “The economics of superstars” (Ex: a r rahman classical hits for Rs 100 or Joshua Julias guitar melodies for Rs 90; Microsoft Vs Apple ; 3 idiots (Life is a race, Rs 240 Crs gross sales in first week) Get the web link of the most common words
  • Get the exponential laws in web from the video Wealth distribution, book sales, hits of websites, frequency of words, telephone calls received, magnitude of earthquakes, population of cities &* add market charts- daily, monthly and yearly &* add gud designs of fractal geometry &* Give them one exercise to draw a simple fractal
