Outcome versus Process
My Sunday Washington Post Business Section column is out. This morning, we look at whether you should be outcome or process focused.The online version used the descriptive headline You’re obsessed with outcomes. Here’s why attention to process pays off while the print version had the more nuanced “So you won — but let’s talk about your game.”
The focus on outcome over the more subtle process is a common error made by sports fans and
investors alike. The column looks at why this is problematic, and what you
should do about it.
Here’s an excerpt:
“Process is simply the methodology used to accomplish an undertaking. It could be a simple checklist or a complex systematic approach. Process focuses on the specific actions that must be taken, regardless of the results.
The column focuses on how why those investors
who focus on outcomes over process are looking at the wrong things.
Love the graphic, too!

Sports fans and investors tend to make similar errors.
Perhaps the biggest is focusing on outcomes rather than process. Sports fanatics
are all Monday morning quarterbacks; they can read you chapter and verse — after
the fact — what should have been done late in the game on 4th and goal from the
2-yard line.
It’s
called hindsight bias, and it afflicts investors, too. They can tell you what
asset classes you should have owned last year, which hedge fund manager you
should have invested with 20 years ago, and why you should have bought Netflix,
Tesla and Apple about 5,000 percent ago. (Thanks for nothing!)
So
what is process, and how does it differ from outcome?
Process
is simply the methodology used to accomplish an undertaking. It could be a
simple checklist or a complex systematic approach. Process focuses on the
specific actions that must be taken, regardless of the results.
Outcome
is the result; it could be due to skill, luck, intelligence or many other random
factors. At the end of the day, outcome is who won or who lost the game, how
many planes landed safely, what stocks went up or down and what surgical
patients lived or died.
In
sports terms, think of process as your playbook and outcome as the final score.
In investing, process is your approach, investment style, discipline and
consistency, while outcome is your return or performance.
Imagine
you are watching two people in a coin-flipping contest. One of them flips 10
heads in a row; the other’s are more random — heads, tails, tails, heads, tails,
etc. Are you willing to bet a substantial sum that the first flipper’s next toss
will be heads? If you said yes, you are outcome focused.
It
seems brazen, yet that is exactly what many investors do. They chase the hottest
coin flipper of the moment. In finance, that is the person with a “hot hand” —
the mutual fund whose manager just finished a great streak, someone who ended up
on the cover of a magazine, or any recent award winner.
If
you have not analyzed and understood a manager’s methodology, how can you
possibly know whether the results are due to skill or chance? We are all too
often, to quote Nassim Taleb, fooled by randomness.
Successful
results in investing could very well be a mere coincidence — a result without
any underlying causation on the manager’s part. Meaning, the outcome was not the
result of process, but rather, dumb luck.
Perhaps
that manager’s investing style (momentum, value, trend following, etc.) came
(temporarily) back in vogue. Maybe his sector became red hot, or the part of the
world he focuses on is seeing a (temporary) boom. What looks like personal
greatness very often is not (and vice versa).
This
is not to say you should always ignore bad outcomes. A series of poor results
may indicate an issue with process.
Ironically,
investors as a group have a tendency to attribute their own successes to the
skill and insight they possess; at the same time, any losing investments are
blamed on bad luck. That’s outcome focus married to ego, and it’s not how you
make money in the markets over the long term.
Why
are we so easily fooled by random outcomes? The pattern recognition subroutine
in your brains evolved to identify threats. That shadow in the tall grass might
be a predator waiting to make you its lunch. Hence, generating false positives
means that you might be wrong 99 of 100 times, but on the savannah, that 100th
event saves your life.
People
tend to be outcome focused, often to the detriment of choosing a good process.
Perhaps another example from outside of the world of finance might be
helpful.
Imagine
you have a medical condition that requires surgery. It’s a bit tricky, but the
procedure has a good chance of success. You interview a few doctors, looking at
their academic history, published papers, experience and reputations. You narrow
the list to two surgeons and get access to their surgical records, including
patient survival rates.
Both
surgeons have very good reputations; one works primarily for private patients
covered by insurance, the other is at a top medical school. The private doctor
runs a success/survival rate of 86 percent, while the medical school doc runs
less than 60 percent.
Which
doctor do you choose?
If
you immediately said the 86 percent doctor, you are outcome focused. You saw the
better results and that was all you needed to know.
Others
might have wondered why a cutter with a great reputation at a top-ranked medical
school had a much worse survival ratio. So you do a little more research into
his process. You find that he invented this procedure 20 years ago. He did all
of the early experimental surgeries, including lots of clinical failures
(meaning bad surgical outcomes). But he refined the surgery, where through trial
and error he developed what is now a life-saving technique. Indeed it has since
become standardized, thanks to him. Every doctor and patient who followed
afterward benefited from his groundbreaking clinical work
Because
of his background and work in this area, this doc gets all of the “impossible”
surgical cases. When other surgeons don’t think they can do the operation — or
don’t want to — they refer it to his medical school. Hopeless and complicated
surgeries make up a big part of his practice. People travel from around the
world just to have this surgeon do this procedure on them. He has seen every
variation of patient, and because of this, he has done more of these operations
than anyone in the world.
Based
on this new information, which surgeon would you choose? The first doctor was
pretty good, but the second doctor is outstanding! If you suddenly are thinking
about the medical school doctor with the lower success rate, well,
congratulations — you have just become process focused.
The
key to becoming more process focused is to understand that good outcomes follow
good processes. Without understanding the underlying process, good outcomes
could just as likely be due to blind luck as to skill.
You should be reminded of this every time you read the
disclaimer “past performance is no guarantee of future results.” What you are
actually seeing is an admission about random outcomes. Past performance is no
guarantee of future results if the past performance is just as likely the result
of luck as it is the result of skill.
Luck
= outcome, and skill = process.
We
never really know what the source of a good outcome is; however, we have a high
degree of confidence what the probabilities are for a good process. A strong
process is a guarantee — not of outcome or results, but of the highest
probability of obtaining desired results. That’s why it is so important to
investors.
