Tathagat Varma MENTAL MODELS
“Mental models are deeply ingrained assumptions, generalizations, or even pictures or images that influence how we understand the worlds and how we take action. Very often, we are not consciously aware of our mental models or the effect they have on our behavior .”
- The Fifth Discipline, Peter Senge,
WHAT IS A MENTAL MODEL?
“…an explanation of someone's thought process about how something works in the real world. It is a representation of the surrounding world, the relationships between its various parts and a person's intuitive perception about their own acts and their consequences. Our mental models help shape our behavior and define our approach to solving problems (akin to a personal algorithm) and carrying out tasks”
- Wikipedia
MENTAL MODELS…
• Mental models are subtle but powerful. Subtle, because we usually are unaware of their effect. Powerful, because they determine what we pay attention to, and therefore what we do.
• Mental models are strongly conservative: left unchallenged, they will cause us to see what we have always seen: the same needs, the same opportunities, the same results. And because we see what our mental models permit us to see, we do what our mental models permit us to do.
MENTAL MODELS…
“What is real? How do you define real? If you're talking about what you can hear, what you can smell, taste and feel then real is
simply electrical signals interpreted by your brain” – Morpheus, Matrix (1999)
ARE MENTAL MODELS REAL?
• “Essentially all models are wrong, but some are useful” – George Box
• “…The problems with mental models lie not in whether they are right or wrong – by definition, all models are simplifications. The problems with mental models arise when they become implicit – when they exist below the level of our awareness…because we remain unaware of our mental models, the models remain unexamined. Because they are unexamined, the models remain unchanged. As the world changes, the gap widens between our mental models and reality, leading to increasingly counterproductive actions” – The Fifth Discipline
ARE MENTAL MODELS RIGHT OR WRONG?
• “…Mental models of what can or cannot be done in different management settings are no less deeply entrenched. Many insights into new markets or outmoded organizational practices fail to get put into practice because they conflict with powerful, tacit mental models” – The Fifth Discipline
• “…the most crucial mental models are those shared by key decision-makers. Those models, if unexamined, limit an organization's range of actions to what is familiar and comfortable.”
CAN MENTAL MODELS IMPACT ORGANIZATIONAL PRACTICES?
LET’ EXAMINE SOME MENTAL MODELS
OSTRICH SYNDROME: “THE PROBLEM WILL GO AWAY IF I IGNORE IT”
IT’S OK TO REACH LATE FOR MEETINGS
BABY ELEPHANT SYNDROME: “I CAN’T BREAK FREE”
BOSS SHOULD HAVE MORE EXPERIENCE
GUESS THE COLORS
Is BLUE a color?
WORK SHOULD BE SERIOUS
THEY ALL WANT TO BE MANAGERS
• Working overtime • Adding more people • New tools • Re-architecture • New programming
language • …New Silver Bullet!
WE WILL MAKE UP FOR THIS DELAY BY …
• Customers who complain are just troublemakers • People leave jobs for higher salary • The Customer is always right • Sitting late in office shows commitment • Gen Y is irresponsible • …
LET’S EXPLORE MORE MENTAL MODELS…
CAN MENTAL MODELS KILL INNOVATION?
ALL PROBLEMS ARE THE SAME
I KNOW WHAT MOTIVATES MY TEAM MEMBERS
I KNOW HOW TO LEAD MY TEAM MEMBERS
• GM is in the business of making money, not cars • Cars are primarily status symbols. Styling is therefore
more important than quality • American car market is isolated from rest of the
world • Workers don’t have an important impact on
productivity or product quality • Everyone connected with the system has no need for
more than a fragmented, compartmentalized understanding of the business
LONG-STANDING AND UNQUESTIONED MENTAL
MODELS AT GM
The "ladder of inference” - a term coined by Professor Chris Argyris - is a metaphor that shows how rapidly we can leap to knee-jerk conclusions with little data and no intermediate thought process, as if rapidly climbing up a ladder in
our minds.
You start at the bottom
with the observable
data,
which is so self-evident that it would show up on a
videotape recorder (Larry has yawned at a
meeting),
and within the space of a few seconds, leap
up to assumptions
(Larry is bored),
to more generic
conclusions (Larry doesn't care about this
project).
Since most of these
conclusions are never discussed
openly, there is no way to
check them.
LADDER OF INFERENCE
LADDER OF INFERENCE
The ladder of inference explains why most people don't usually remember where their deepest attitudes came from. The data is long since lost to memory, after years of inferential leap
EXAMPLES

• Reflection: Becoming more aware of your own thinking and reasoning
• Advocacy: Making your thinking and reasoning more visible to others
• Inquiry: Inquiring into others' thinking and reasoning
HOW TO USE LADDER OF INFERENCE?
If mental models can impede learning – freezing companies and industries in outmoded
practices – why can’t they also help accelerate learning?
HOW CAN WE USE MENTAL MODELS FOR POSITIVE RESULTS?
• Skills of reflection concern slowing down our own thinking processes so that we can become more aware of how we form our mental models and the ways they influence our actions
• Inquiry skills concern how we operate in face-to-face interactions with others, especially in dealing with complex and conflict issues.
SKILLS
• Facing up to distinctions between espoused theories (what we say) and theories-in-use (the implied theory in what we do)
• Recognizing “leaps of abstractions” (noticing our jumps from observing to generalization)
• Exposing the “left-hand column” (articulating what we normally do not say)
• Balancing inquiry and advocacy skills (skills for effective collaborative learning)
TOOLS
• Powerful technique for beginning to “see” how our mental models operate in particular situations.
• It reveals ways that we manipulate situations to avoid dealing with how we actually think and feel, and thereby prevent a counterproductive situation from improving.
LEFT-HAND COLUMN
• Me: How did the presentation go? • Bill: Well, I don’t know. It’s really too early to tell.
Besides, we’re breaking new ground here. • Me: well, what do you think we should do? I believe
the issues you were raising are important. • Bill: I am not sure. Let’s just wait and see what
happens. • Me: You may be right, but I think we may need to do
more than just wait.
EXAMPLE
What I am thinking What is said
Everyone says the presentation was a bomb! Does he really not know how bad it was? Or is he not willing to face up to it? He really is afraid to see the truth. If only he had more confidence, he could probably learn from a situation like this. I can’t believe how disastrous that presentation was to our moving ahead. I’ve got to find a way to light a fire under this guy.
Me: How did the presentation go? Bill: Well, I don’t know. It’s really too early to tell. Besides, we’re breaking new ground here. Me: well, what do you think we should do?

EXAMPLE WITH LEFT-HAND COLUMN
• When operating in pure advocacy, the goal is to win the argument.
• Pure inquiry is also limited. • When inquiry and advocacy are
combined, the goal is no longer to “win the argument” but to find the best argument.
BALANCING INQUIRY AND ADVOCACY
• Make your own reasoning explicit • Encourage others to explore your
view • Encourage others to provide
different views • Actively inquire into other’s views
that differ from your own
WHEN ADVOCATING YOUR VIEWS…
• If you are making assumptions about other’s views, state your assumptions clearly and acknowledge that they are assumptions
• State the ‘data’ upon which your assumptions are based
• Don’t bother asking questions if you are not genuinely interested in other’s response
WHEN INQUIRING INTO OTHERS’ VIEWS…
• As what data or logic might change their views
• Ask if there is any way you might together design and experiment (or some other inquiry) that might provide new information
WHEN YOU ARRIVE AT AN IMPASSE…
