Roulette is different from Russian Roulette
The Logic of Risk Taking
If you do not have time for Taleb's Incerto, read this post. It is the foundation of his thinking and a key insight between what he classifies as an ensemble risk, time-based risk, and ergodicity.
"We saw with the earlier comment by Warren Buffett that, literally, anyone who survived in the risk-taking business has a version of “in order to succeed, you must first survive.” My own version has been: “never cross a river if it is on average four feet deep.” I effectively organized all my life around the point that sequence matters..."
Why does Taleb focus on sequence and average? Because he understands the importance of fat tails. Our brains do a poor job of understanding systems with extremes. Taleb, who popularized the term Black Swan, has made a career in betting on extremes. Understanding that repeatability of exposure means a movement away from a normal curve into a system of fat tail risks is important when considering your options.
Remember 4 weeks ago where everyone could predict the market?
"Now, when you read material by finance professors, finance gurus or your local bank making investment recommendations based on the long term returns of the market, beware. Even if their forecast were true (it isn’t), no person can get the returns of the market unless he has infinite pockets and no uncle points"
Gamble on a Group, Not Yourself
This leads to one of his most famous examples ever given, one of Russian Roulette. It provides a visceral understanding between two types of risk Ensemble and Time-Based risk. Think of Ensemble Risk as the risk on the group of individuals. The second type of risk is Time-Based which is the risk from the view of an individual within the group.
Russian Roulette, much like life, is not ergodic as the individual dies at the end after 1 failure. Most predictions made by theorists you see in the world pretend that ensemble and time-based risk are equal...which is incorrect.
"The central problem is that if there is a possibility of ruin, cost-benefit analyses are no longer possible.
Consider a more extreme example than the Casino experiment. Assume a collection of people play Russian Roulette a single time for a million dollars –this is the central story in Fooled by Randomness. About five out of six will make money. If someone used a standard cost-benefit analysis, he would have claimed that one has 83.33% chance of gains, for an “expected” average return per shot of $833,333. But if you played Russian roulette more than once, you are deemed to end up in the cemetery. Your expected return is … not computable."
What Does This Mean For Advertising
We admit this article is heady. We believe that having a fundamental understanding of how to value the true risk in a situation is paramount for success in life, investing, and even in advertising. With 7MM advertisers on Facebook all vying for roughly the same audience, you have to take some risks to stand out from the herd.
Does your brand need a refresh to stand out? Should you expand your attribution window or include view based conversions? Are you running ROI for profit or for growth? Should you invest in non-standard digital channels that have weaker tracking but potentially stronger virality or EMV potential?
All these decisions have an associated risk and the market winners (those Disruptor companies we all know and love) are the companies that can take on the right kind of risk, survive, and thrive. Our previous write up on Asymmetric Risk, Issue 002, was highly inspired by Taleb's view of the world and is a good double-click if you find this topic compelling.
At the end of the day, we all have to take risks. The key to success is judging what risks to take in life...just be careful of rivers that are on average 4 feet deep.

This write up is part 2 in the series we call Adventures in Significance. After running 257 lift studies across 30+ different clients in our past, we thought it would be helpful to write a series on common mistakes and how to avoid them. This is a dreaded subject by many but is core to the direct response advertising world. We thought we could do our part with a round-up of our favorite opinions on the subject and how this applies to your business.
