There are times when you would need to blend into an environment that’s new to you. Fitting in a region would require a checklist, the first dimension of which is personal. How do your looks and manners stack up to the environment? Travelers who look and act like fish out of the water are prime targets for all types of criminals and agents who make themselves conspicuous are prime candidates for discovery.
The second dimension is to cultivate cultural awareness. This involves constantly weighing actions and preferences against the prevailing cultural context. If majority of the population forgoes mayonnaise on their sandwiches or ice in their drinks, you should follow suit.
Third is situational awareness. In this phase, you continually scans your environment for potential dangers, playing out worst-case scenarios in order to identify which actions to take before the strikes. Within thirty seconds of having entered a restaurant, you should have canvassed all exits and spotted any potential improvised weapons in the vicinity.
The last dimension is third-party awareness. You must always be keenly aware of anyone who might be watching you—whether you’re operating in another country or using the Internet. The goal here is to remain undetected by third parties such as law enforcement officials, citizens, criminals, and even hackers.
