Surrounded by Idiots
A summary
Hey everyone,
I just finished reading “Surrounded by Idiots” by Thomas Erikson two days ago. The book talks about different types of people using colors – Red, Yellow, Green, and Blue. It’s like a fun way to understand how we all have different styles of talking and acting. Whether you’re curious about yourself or want to get along better with others, this book gives cool ideas about how people tick.
At first there’s a very short summary (for the lazy ones). But I highly recommend the summary after this one.
So let’s dive in!
Short summary
Surrounded by Idiots has some great advice on how to get your point across more effectively, communicate better, and work your way up in your personal and professional life by getting to know the four types of personalities people generally have and how to address each one in particular to kickstart a beneficial dialogue, instead of engaging in a conflict.
Communication happens on the listener’s terms. Information is rarely received as the sender conceived it. To communicate effectively, we must adapt our style to the listener’s.
The four types of behaviour. The DISA model suggests there are four core types of behaviour, denoted by four colours (Red, Yellow, Green and Blue).
Adapting and giving feedback to different behaviour types. Reds want direct, respectful communication and space to lead. Yellows want friendly communication and space to innovate. Greens want slow change, recognition and space to recharge. Blues want accurate detail and a focus on facts.
Complementary and challenging combinations. The most challenging combinations are the behavioural opposites (Blue & Yellow and Red & Green).
Stress factors and response of behaviour types. Each behaviour type has different stress triggers and handles stress differently.

The REAL Summary
First: DISA stands for Dominance, Inducement, Submission and Analytic Ability. These four terms are the primary types of behaviour, and each is associated with a colour (Red, Yellow, Green and Blue, respectively).
Communication happens on the listener’s terms
When we convey a message, the person receiving it interprets it through their own filter, seldom grasping it exactly as intended. Put simply, our messages often don’t land as we originally intended.
This shows us the importance of adjusting our communication to align with the behavioral tendencies of the recipient.
“You help other people understand you by creating a secure arena for communication – on their terms. Then the listener can use his energy to understand rather than to consciously or unconsciously react to your manner of communicating.”
There are just two situations where you can communicate effectively without adapting:
When you are alone in the room.
When all the other people in the room are exactly like you.
The rest of the time we should consider other’s behaviour, embracing the power of diverse teams over singular behaviour types.
“Behaviour patterns are like a toolbox. All types are needed. Depending on the occasion, a tool can sometimes be right and sometimes be wrong. A thirty-pound sledgehammer is great for tearing down walls, but it’s hardly the thing you want to hang a picture in the foyer.”
Our behaviour types are the result of heredity and environment. This idea can be visualised as an onion of several layers.

Core Values: Deeply embedded beliefs for which it is almost impossible to change, often embedded by parenting.
Attitudes and Approaches: Things we’ve formed opinions on based on our own experiences.
Core Behaviour: Core values and attitudes form our core behaviour, which is how we act when there is no external influence.
Moderated Behaviour: People around us tend to see our moderated behaviour, however, whereby we adapt to the situational context.
Environment: These adjustments are all influenced by the outer layer of our environment.
The trick of communication is to figure out what is under the surface to understand core behaviour types.
The four types of behaviour
The DISA model is a popular and simple way of assessing types of behaviour, breaking out behaviour types into four colours as per the below image: Red, Yellow, Green and Blue.

🔴 Red Behaviour
Core Traits: Reds are highly ambitious and driven, competitive and comfortable taking the lead. They speak their minds and prioritise speed and efficiency. They have a strong conviction in their version of reality.
Perception: Reds can be seen as dictatorial, controlling and tyrannical. They might not seem interested in trivial conversation and tend to be focused on the topics that matter. Often this blunt communication can come across as aggressive.
Body Language: Reds exhibit clear and distinctive body language. They keep their distance from others, have powerful handshakes, often lean forward aggressively, make direct eye contact and controlling gestures, and speak quickly with a strong voice.
🟡 Yellow Behaviour
Core Traits: Yellows are relentlessly optimistic and often the most popular of the behaviour types. Their focus is on developing relationships and they are highly persuasive. Yellows generally exhibit a high level of energy and curiosity.
Perception: Conversations with Yellows are often one-sided streams of unprocessed thoughts. Yellows typically turn conversations to themselves and are very poor listeners. They are often seen as careless with projects that require longer spells of concentration and significant follow-up.
Body Language: Yellow body language is relaxed and tactile, eye contact is friendly, and gestures are expressive. Yellows often come close, smile a lot, and talk quickly and empathetically.
🟢 Green Behaviour
Core Traits: Greens don’t stick out like other behaviour types. They are calm and tolerant to singular behaviour, friendly, and considered strong team players. They often struggle to say no and are less direct and upfront.
Perception: Greens are obstinate once a decision has been taken. They can also be considered enthusiasm killers through indifference, and their behaviour can appear passive and disinterested. Greens may also be less precise and more non-committal with words in order to preserve relationships.
Body Language: Green body language is relaxed and close. They often tend to lean backwards, make very friendly eye contact, small gestures, and less flamboyant movement. Green voices don’t tend to be strong, but instead soft and slower talking.
🔵 Blue Behaviour
Core Traits: Blues are logical analysts, cool headed, risk-averse and detail-oriented. They are more willing to work on predictable tasks and are usually introverted.
Perception: The ultimate perfectionists, blues are not keen on small talk and can appear cold and dismissive. Their fixation on details and checking may also suggest they don’t trust others, as well as leading to slower decision making.
Body Language: Blues prefer distance. Their body language tends to be closed, with direct eye contact, speech without gestures, and a subdued and slow voice.
Adapting and giving feedback to different behaviour types
In a perfect world, we can all exhibit our core behaviours. But the reality is that we won’t always get through to others unless we adapt, as well as adjusting our feedback style.
🔴 Reds
Adapting to Reds:
Be quick and brief
Cut the small talk
Focus on the essentials
Don’t sit on the fence – have a clear opinion
Demonstrate hard work
Confront if behaviour crosses a line
Remind that speed doesn’t always produce the right results
Giving Feedback to Reds:
Be upfront and honest – don’t sugarcoat feedback
Give concrete examples
Stick to facts over feelings
Be prepared to calmly handle conflict
Repeat what was agreed
🟡 Yellows
Adapting to Yellows:
Create a warm and friendly atmosphere around them
Strip away unnecessary detail and focus on the big issues
Empathise with gut-based decisions
Give them space to work on new projects
Become approachable (e.g. through open body language)
Check they have listened
Giving Feedback to Yellows:
Prepare a feedback agenda and stick to it
Don’t let them eat up the time
Give concrete examples
Be aware that they might not be fully listening
Ensure they don’t take it personally – behaviour not person
Get them to repeat what you’ve agreed
🟢 Greens
Adapting to Greens:
Be prepared to listen to what they are anxious about
Allow them periods of peace and quiet to recharge
Clearly explain the steps of a plan
Deliver criticism in private
Take command to get things done where needed
Giving Feedback to Greens:
Give concrete examples
Adopt a gentle approach – Greens can take things very badly
Explain the behaviour is the problem, not the person
Get them to repeat what you’ve agreed
🔵 Blues
Adapting to Blues:
Do your homework
Stick to the task and small talk
Stick to the facts and avoid daydreaming
Provide the necessary detail
Remind them that sometimes speed is the priority
Giving Feedback to Blues:
Provide specific and detailed examples
Avoid getting too personal
Stick to facts
Be prepared for counterquestions in great detail
Get them to repeat what was said and follow up
Complementary and challenging combinations
In a perfect world, we’d have a team that is a blend of all the colours, but there are cases where this inevitably won’t be the case. Here it’s important to understand the natural and complementary combinations, as well as the challenging combinations.
Natural Combinations: Blues and Greens have some natural synergies. Both are introverted and so feel secure with one another. Reds and Yellows have natural synergies for opposite reasons. Both have the same type of energy and enthusiasm for working quickly.
Complementary Combinations: Reds and Blues are both task-oriented, with one results-focused and one detail-oriented. Yellows and Greens are more relationship-oriented, with Yellows being great talkers and Greens great listeners.
Challenging Combinations: Opposite colours tend to be more challenging. Reds and Greens can be a difficult combination. The directness of Reds may frustrate Greens, while the passivity and slowness of Greens may frustrate Reds. The most challenging combination, however, is Blue and Yellow. There is typically friction from the outset, with one focused quietly on detail and the other talkative and shooting from the hip.
When it comes to the optimal combinations, Erikson has some simple advice. If it’s not clear what behaviour type you are working with, sometimes it’s best to listen for a while. Often, acting Green is the best default strategy if you’re unsure.
The stress factors and stress response of behaviour types
The colours can also give us a good idea of what causes stress for people and how they typically respond to stress.
🔴 Reds
Red Stress Factors: Taking authority away; achieving no results; no challenge; wasting time and resources; mundane and repetitive tasks; making stupid mistakes; lack of control.
Red Stress Responses: Work even harder; hide themselves away; identify scapegoats.
🟡 Yellows
Yellow Stress Factors: Feeling invisible; scepticism; structured work; isolation from the group; “overthinking”; public humiliation.
Yellow Stress Responses: Seek attention even more; excessive optimism; new ideas.
🟢 Greens
Green Stress Factors: Uncharted territory; unfinished tasks; lack of private space; rapid change; being in the spotlight
Green Stress Responses: Cold, closed body language; uncertain and insecure; internalise blame for mistakes.
🔵 Blues
Blue Stress Factors: Having knowledge challenged; spontaneous decisions; uncertain and risky decisions; mistakes; emotional people around them
Blue Stress Responses: Excessive pessimism; lethargy; slowing down to avoid mistakes.
Thanks for checking out the scoop on “Surrounded by Idiots” with me. Learning about different types of people and how they talk is pretty cool, right?
Just remember, adjusting how we talk helps us get along better. Whether you’re more of a Red, Yellow, Green, or Blue kind of person, let’s keep making friendships awesome.
