To forecast the future, marketing leaders often look to the past. But the past isn’t always a very reliable gauge of future conditions. For proof, we need to look back to a day-in-the-life of a turkey, and implications of not preparing for possible “extreme” events around the corner.
First, let’s start with a fun exercise courtesy of Wilmott Magazine. Let’s look at damage estimates of earthquakes in California from 1970 to 1993 in the table below. Can you make an educated calculation of losses due to earthquakes in 1994?
Taking a look at the distribution of data, notice the low end is “0” and at high end, the most damage caused was “129”. So what’s your guess?
If you’re like me, you probably guessed wrong. Using the above numbers as an “anchor”, most people would reasonably assume that 1994’s earthquake was either an average of the above numbers or perhaps a bit higher than 129. Maybe you even threw out “129” as an outlier in the dataset. To be honest, I guessed around “200”.
The correct answer is “2217.2”! FEMA estimates that every year earthquake losses in the United States add up to $4.4 billion a year. But then, some extreme outliers can really skew that number, especially years like 1994 where just the Northridge Earthquake in California alone tallied $20B in damage!
Let’s get back to talking turkeys via a parable from Nassim Taleb, author of the “Black Swan”. Dr. Taleb reminds us that fat, dumb and happy is probably the best way to describe the life of a turkey. They’re fed and nurtured for three years straight. Day after day, they expect the same thing. But then, one fateful day arrives and the “life” of a turkey ends quite abruptly.
Can we accurately predict the future based on reviewing and analyzing historical data? Sometimes, but we have to make assumptions of similar conditions, a normal distribution, and event independence. Complex systems will have none of these characteristics. Dr. Taleb says as much; “Real life isn’t a casino.”
Indeed, the parable of the turkey and the earthquake loss estimation exercise show us that predicting the future in complex systems can be a futile exercise because there are so many unknowns, changing conditions, and inter-connecting relationships. Extreme events that carry a huge impact happen, and some would argue they’re happening a whole lot more often as interlocking financial markets and globalization become commonplace.
Should prediction exercises be avoided? Nassim Taleb would argue otherwise; “We need to start thinking of the inconceivable,” he says. And while we cannot determine the exact probability of tomorrow’s events, we can “get a general idea about the possibility of their occurrence.”
And that’s where scenario planning comes into play. Bill Ziemba, author of the aforementioned Wilmott Magazine article says, “Getting all the scenarios and their probabilities right is impossible and doesn’t matter much anyway. What is important is to cover the board of possible occurrences. Then you will make sound decisions with risk under control.”
The fact is, like the turkey, we just don’t know what tomorrow will bring. So, plan for the five to seven most likely occurrences and then develop contingencies based on those scenarios. French microbiologist Louis Pasteur says it best, “In the fields of observation chance favors only the prepared mind.”
For a turkey, today may appear like any other “normal” day. However, tomorrow could be the chopping block.
Questions:
- Nassim Taleb says, “It is only in very rare circumstances that probability (by itself) is a guide to decision making.” Does this mean that historical data analysis isn’t worth the effort?
- If chance favors the prepared mind, what’s the “next unexpected twist” that marketers should be looking for?
Strategic planning isn’t sexy. That said, bear with me.
In a challenging global slowdown, the world seems awash in capacity. Scans of major business publications show airlines reducing flights, companies furloughing or firing employees, and manufacturers closing plants. If you agree that it appears there is more unused capacity than demand, why should 
When forecasting in marketing, pay attention to dissent, especially when common knowledge or popular opinion says otherwise. More than a few CEOs and economists predicted the credit bubble of 2008 bursting in a big way and were mocked.
Marketing executives should have a pulse on shifting consumer preferences, macro-economic conditions and emerging competitors. However, in forecasting the financial crisis of 2008 and beyond, most marketers (and economists for that matter) failed to accurately “call” the collapse, even though signs of catastrophe were ubiquitous.
Will tomorrow be like today? In planning assumptions for budgeting and forecasting, most marketers believe that events of tomorrow, next week and next year will be much like this year, or years past with just slight deviation.
No doubt, we live in volatile times. The complexity, interconnectedness and intricacy of global markets is causing executives around the globe to check decisions once, twice and even delay important decisions because they cannot “peer around the corner.” Some marketing executives are asking themselves, “What are the odds of…” to help make tough decisions. Others are saying, “We’re in a new paradigm,” and “the past is no longer relevant.” How are you making critical decisions?
