Summary of "How Culture Drives Behaviours | Julien S. Bourrelle | TEDxTrondheim"

Main thesis

Culture shapes how people perceive and behave: everyone views the world through “cultural glasses” (a cultural lens). Changing that lens changes how you interpret others’ behavior and how well different groups can work together.

To benefit from diversity you must move beyond reacting with resistance or withdrawal and instead observe, learn and adapt.

Illustrative stories and their lessons

Brussels vs Norway

Story: A stranger speaking to the speaker in Belgium felt normal given his Canadian/French-speaking background but was surprising in Norway.
Lesson: Relocation rewires expectations; different cultures have different social “frames.”

Catalonia cava tour

Story: A neutral facial expression from a tall, blond friend was read by the cava guide as disinterest.
Lesson: Emotional expressiveness norms differ; people interpret others through their own cultural expectations.

University leadership class

Story: The speaker, a man, was excluded from a “Leadership for women” course intended to fast-track women into professorships.
Lesson: Policies that enforce equality of result can change opportunities; cultural and policy choices affect diversity outcomes.

Bus-stop / bench example

Story: Misunderstandings over seating and personal space.
Lesson: These can look like rejection or prejudice when they are really differences in interpersonal distance norms.

International conference “dance”

Story: South Americans tend to stand closer; North Europeans stand farther apart.
Lesson: Personal space and politeness norms vary and create predictable miscommunications.

Why cultural diversity matters (evidence and benefits)

Cultural diversity improves group performance: examples cited in the talk include boards with gender mix performing ~15% better and boards with cultural diversity performing ~35% better.
The main challenge to realize these benefits is effective communication: making cultural differences visible so people can adapt, thereby boosting problem-solving, creativity, and innovation.

Concepts and frameworks introduced

Three ways to relate to a new culture:
1. Confront: insist your behavior is right.
2. Complain: isolate yourself in foreigner-only bubbles.
3. Conform (recommended): observe, learn, understand, and adapt your behavior to fit the society to truly benefit from diversity.
Individualism vs collectivism:
- Collectivist cultures stress interdependence and expect close, constant social involvement (strong, symbiotic friendships).
- Individualist cultures value independence, accepting more distance and silence as normal in friendships.
Politeness as culturally defined:
- Norms of politeness (how to speak, how much space to leave, what counts as respectful behavior) differ across cultures; without explanation newcomers will misread expectations.

Practical steps / methodology to benefit from cultural differences

Observe
- Watch everyday behavior: greetings, proximity, bus/bench behavior, emotional expressiveness.
Learn and ask
- Seek explanations about local norms: what politeness means, appropriate personal space, emotional feedback cues.
Understand your own cultural lens
- Reflect on how your expectations shape your interpretations of others.
Adapt your behavior where appropriate
- Modify verbal and nonverbal cues to reduce miscommunication (adjust proximity, eye contact, expressiveness).
Communicate explicitly about differences when needed
- Explain cultural expectations in group or organizational settings to improve collaboration.
Avoid defensive reactions
- Don’t automatically assume other peoples’ behaviors are wrong (don’t confront).
- Don’t retreat into segregated groups (don’t complain).
Use simple, humorous, visual tools to teach and reduce friction
- Example: drawings, a Facebook page and a website that explained cultural situations and reached over one million views — a scalable awareness-building approach.
Take small steps consistently
- Incremental changes in perception and behavior can accumulate into better intercultural relations.

Takeaway

Misunderstandings are often cultural, not personal. By consciously shifting your cultural lens—observing, learning, and adapting—you and your organizations can unlock the problem-solving, creativity, and innovation benefits of diversity.
