World-class investors improve the quality of their decisions with this technique…
So do top CEOs and entrepreneurs.
Military leaders use it. So do wedding planners. So do business executives of all kinds.
Just about any time you have a complex scenario with a wide range of outcomes – which is certainly the case with investing – this technique has value.
The bigger the decision or the higher the stakes, the more crucial it becomes.
This incredibly useful technique is called the “premortem.”
It’s related to the better-known concept of a “postmortem,” but it comes with a few important twists…
“Postmortem” literally means “after death.” In the medical field, a postmortem is an examination into how a patient died and why.
The goal of a postmortem is to learn what happened and why it happened – and hopefully, to achieve better results next time. As the old joke goes, everybody benefits from a postmortem except the patient.
In business or investing settings, you can do a postmortem to examine what went wrong with a project or investment after it has failed. The goal is the same: to learn what caused the failure and, hopefully, do better next time.
A premortem is like a postmortem, but with one big difference: The premortem takes place before the investment (or project) has failed.
Ideally, it takes place before the investment or project even starts.
With a premortem, you imagine that “the patient has died” – that an investment idea crashed and burned or that a project has failed miserably.
That’s the first step… before you do anything else.
After picturing this worst-case-scenario outcome, you then ask the question: “How did the failure happen?” From that point, you work backwards from different potential failures and create a list of causes for what went wrong.
And then – because the negative outcome hasn’t actually happened yet – you use this list of “what went wrong” items to failure-proof your project or your investment, increasing the odds that it will succeed.
The premortem was popularized as a planning technique by Dr. Gary A. Klein, a specialist in decision making and cognitive task analysis.
He got the idea from a 1989 study, conducted by researchers at Cornell, the University of Colorado, and the Wharton School.
The 1989 study showed that “prospective hindsight” – picturing a future scenario and imagining it already occurred – increased the accuracy of pinpointing reasons for future outcomes by 30%. The subjects had a specific outcome to work with… instead of a vague mass of possibilities. So they came up with longer explanations for what happened, with more concrete, specific causes.
The reason the premortem works is because it forces the brain to exercise its creative muscles and break out of normal channels.
With normal prediction habits, where someone is asked what he or she expects to happen around a given investment, it is easy to stumble into psychological pitfalls… like overconfidence, confirmation bias, and more.
The premortem technique takes the brain to a new place. If you genuinely try to imagine failure has already occurred, and then try to work out why, your subconscious will organize its agenda in a different way.
This can help you generate new insights, see risks and problems more clearly, or identify factors that you would otherwise miss.
- A smart investor can use the premortem in at least two ways:
- To think about what might go wrong with an investment in advance.
To think about what steps you will take, planned out ahead of time, if the worst happens.
These steps can be as simple as a list of rules laid out as “if/then” statements. For example:
If Investment X hits the TradeStops trailing-stop alert, I will automatically sell my shares (or my broker will).
Making a predefined list of rules makes use of the premortem in another interesting way… It anticipates “what could go wrong” with an investor’s own emotional state.
The worst time to prepare for a crisis is smack-dab in the middle of one. When the crisis is occurring, emotions are high and distractions abound, making it hard to think clearly.
If you decide what to do in advance, you can take action calmly when the time comes – without having to make new decisions under stress.
That’s why creating a set of risk-management rules increases the odds that you will follow your plan when disaster strikes.
This, in turn, helps you preserve your capital and increases your chances of success. That’s why I created my TradeStops software… It offers a simple set of tools to help investors plan their trades – and manage their emotions.
It may sound pessimistic, or even gloomy, to focus on failure before you even begin. But working through the risks beforehand and making a plan to deal with them is not pessimistic at all.
It’s a practical solution that will boost your odds of success. So make sure you’re using it to plan your investments today.
