On April 10, 2003, Pepsi announced a contest called “The Pepsi Billion Dollar Sweepstakes”. It was scheduled to run for 5 months starting from May in the same year.

For the contest, Pepsi printed one billion special codes which could be redeemed either on their website or via postal mail. According to Pepsi’s estimate, about 200-300 million of these codes were redeemed. Out of these, 100 codes were chosen in a random draw to appear in a two-hour live gameshow-style television special. Each of these 100 people were assigned a random 6-digit number, and a chimpanzee (to ensure a truly random number and of course to rule out any monkey business) backstage rolled dice to determine the grand prize number. This number was kept secret and the 10 players whose numbers were closest to it were chosen for the final elimination. On the evening of September 14, the final day of the contest, the event, titled Play for a Billion, was aired live. If a player’s number matched the grand prize number, he would win US$ 1 billion.

Given the scenario, it was highly unlikely that anyone would win a billion dollar. The chances were literally 1 in a billion. In spite of that, Pepsi was unwilling to bear the risk of the possible billion-dollar prize. So they arranged for an insurance company to insure the event. They paid US$ 10 million to Berkshire Hathaway to assume the risk. Yes, Warren Buffett’s Berkshire Hathaway. The same guy who is famous for his two iron rules –

1. Never lose money
2. Don’t forget rule number 1.

Then why would Buffett expose his company to such a big risk for a relatively paltry premium of US$ 10 million? Isn’t this akin to playing Russian roulette?

In January 2016, after two months of paternity leave when Mark Zuckerberg returned to work he asked his followers, showing off a picture of his wardrobe, for a suggestion about what he should be wearing to office. This is how his wardrobe looked.

Pretty drab collection, isn’t it? Zuckerberg has been wearing the same outfit, a grey t-shirt, for many years. The reminds us of Steve Jobs and his favourite black turtleneck.

So why do these billionaires who could afford almost anything in this planet, choose to stick to a simple attire?

The answer is – it’s their hack to simplify life.

According to Zuckerberg, making clothing decisions each day was a “frivolous” waste of time. I really want to clear my life, says Zuck, “to make it so that I have to make as few decisions as possible about anything except how best to serve this community.”

According to one estimate, we normally make somewhere around 35,000 decisions every single day. Many of those decisions are unconscious like walking, blinking, breathing and don’t need any extra mental effort. But the sheer volume of even those decisions that require at least some brain power like what to wear, where to eat, how to get to work, who to call when you get there, is staggering.

“What is not started today is never finished tomorrow.” ~ Johann Wolfgang von Goethe

The most interesting and exciting thing about psychology is that you don’t need expensive lab instruments to experimentally test the validity of theories. The world is your lab and its inhabitants i.e., people, including yourself, are the test subjects (read guinea pigs).

So here is a simple experiment that you can try during your next visit to any restaurant.

You’d often find waiters who don’t need to write down your order. They seem to have this remarkable ability to accurately remember the order for each table. Even if there are half a dozen orders with every order consisting of many different dishes (including special request like – less sugar, no mushrooms in the Pizza etc.) these waiters rarely goof up.

Well, it’s a part of their job and with years of practice, they develop a super-sharp memory. But do they really have a great memory?

Try this – After you are done with your meals and have paid the bills (and a good tip), wait for ten minutes after you have left your table and then go back to the waiter who was waiting on you. Ask him to repeat your order. You’d expect him to rattle off your order without any difficulty. But don’t be surprised if he gives you the look – “I am sorry, who are you?”

It would seem, not just your order but your whole existence has evaporated from waiter’s memory. What happened to his super memory?

On June 16, 2015, Donald Trump announced his candidacy for President of the United States. Most political forecasters and pundits brushed this news as Trump’s another gimmick for seeking attention and creating sensational news.

Sixteen months later, as November 2016 approached, it became frighteningly clear that Trump was very close to winning the elections.

However, when the experts were shaking their heads in disbelief and talking about all the things that were wrong with Trump, there was a cartoonist in San Francisco who had been writing blogs all through 2015 and 2016, claiming that Trump will win the elections in landslide. He received a lot of flak (even threats) but on November 8, 2016, Scott Adams, the creator of Dilbert was proved right.

Not entirely right because Trump’s victory wasn’t exactly a landslide but he did win the elections. But Adams was way ahead than the experts who were sweating over predicting precise numbers by which Trump will lose.

Charlie Munger likes to say, “It’s better to be approximately right than precisely wrong.”
