Cognitive biases affect how we acquire, interpret, and process information. When we make decisions, they cause systematic deviations from rationality. Although cognitive biases enable us to address issues more rapidly than we could using strict logic, they can cause us to make epically bad decisions. These properties make cognitive biases useful as tools of influence, especially when the goal of the influencer is not what others might regard as objectively justifiable on rational grounds.
Familiarity with this use of cognitive biases helps limit the incidence of abuses. Here's Part I of a catalog of influencing techniques that exploit cognitive biases.
- Outcome Bias
- The Outcome Bias is the tendency to evaluate a proposition based not on its general validity, but instead on a known outcome in one or more specific instances. For example, we might not adopt a particular technological solution if we believe that it failed in some previous application, even in the absence of a sound argument that the current proposal would yield analogous results.
- To limit the effects of Outcome Bias, require that advocates restrict their arguments to the application at hand, without reference to past outcomes. If people want to use such data, require that they demonstrate applicability on strict logical grounds.
- Cascade effects
- Some cognitive biases belong to a grouping that can be called cascade effects, in which an idea propagates largely because members of a group observe its adoption by other members of the group. Two of these phenomena are the Availability Cascade and the Bandwagon Effect. Groupthink, the Abilene Paradox, and Peer Pressure can also be understood in terms of cascade effects. Influencers who wish to exploit cascade effects might seek to influence "thought leaders" first, and then use their endorsements to persuade others.
- To determine Familiarity with the use of
cognitive biases as tools of
influence helps limit the
incidence of abuseswhether cascade effects are in play, track the sequence of conversions among adopters of the advocated proposition. If the early adopters are thought leaders, but are not the authors of the proposition, it's possible that the authors are employing cascade effects.
- Dunning-Kruger Effect
- The Dunning-Kruger Effect is the tendency to err in assessing either our own competence, or the competence of others. The more expert we are, the greater is our awareness of our own limitations; the less expert we are, the more likely we are to rely on our assessment of others' demeanor as a proxy for competence. For example, if people seem to lack confidence, we tend to question their competence. And the more complete is our grasp of a complex situation, the less confident we tend to appear when we express ourselves about it.
- People who consciously exploit this effect might tend to project extreme confidence when they engage in discussions. They know that confidence makes their arguments seem more valid.

- Changing the Subject: II
- Sometimes, in conversation, we must change the subject, but we also do it to dominate, manipulate, or
assert power. Subject changing — and controlling its use — can be important political skills.
- Masked Messages
- Sometimes what we say to each other isn't what we really mean. We mask the messages, or we form them
into what are usually positive structures, to make them appear to be something less malicious than they
are. Here are some examples of masked messages.
- Social Transactions: We're Doing It My Way
- We have choices about how we conduct social transactions — greetings, partings, opening doors,
and so on. Some transactions require that we collaborate with others. In social transactions, how do
we decide whose preferences rule?
- Suspense Is Not Your Friend
- Most of us have to talk to other people at work. Whether to peers, subordinates, or superiors, sometimes
we must convey information that can be complicated when delivered in full detail. To convey complicated
ideas effectively, avoid suspense.
- High Falutin' Goofy Talk: III
- Workplace speech and writing sometimes strays into the land of pretentious but overused business phrases,
which I like to call "high falutin' goofy talk." We use these phrases with perhaps less thought
than they deserve, because they can be trite or can evoke indecorous images. Here's Part III of a collection
of phrases and images to avoid.

- The Power Affect: How We Express Our Personal Power
- Many people who possess real organizational power have a characteristic demeanor. It's the way they project their presence. I call this the power affect. Some people — call them power pretenders — adopt the power affect well before they attain significant organizational power. Unfortunately for their colleagues, and for their organizations, power pretenders can attain organizational power out of proportion to their merit or abilities. Understanding the power affect is therefore important for anyone who aims to attain power, or anyone who works with power pretenders. Read more about this program.
