The more you know about the culture and psychology of your community, the more successful your campaign will be.
The more you know about the culture of the community you want to reach — how they tend to react, how they receive new information, and the things that are important to them — the more likely it is that your message will resonate.
For example, if you want to call a meeting with youth on Facebook in Bangladesh — or with youth pretty much anywhere — you might call it at 11:00 pm because the percentage of people active on Facebook will be high at that time and your post will get lots of engagement. Or, when community organizers in African-American neighborhoods in Los Angeles wanted to distribute key health information, they chose to do it through barbershops and beautyshops because they were trusted community settings”.
Sometimes the best approach is obvious, sometimes it requires research and creativity; in either case, when organizing in a community setting, the better you understand people’s culture, beliefs, traditions and psychology, the more effective your campaign will be.
