Deus Ex: Human Revolution - Social Paths @ Silicon Era

Silicon Era reports on the social or diplomatic opportunities in Deus Ex: Human Revolution.  You'll have to excuse the poor English but here's an example (light spoilers):

Dugas gave an example of the social mechanics can by detailing an unseen part of Deus Ex: Human Revolution.

Deus Ex: Human Revolution has a mission set in Detroit where Adam needs to go into a police station to recover information. Adam can fight his way in or sneaking in through the roof or sewers. If you want to take a non-violent route, Adam can walk through the main lobby and talk to the desk sergeant. “By talking to him you’ll discover there is a background story between your character and his character,” Dugas highlighted. “If you try to convince him to go inside he says ‘I’ll lose my job’, that type of thing. If you pursue that route and win you can access the entire police station.” Pick this path and you won’t have to resort to stealth or fighting.

Later on in the game, Adam may run into the desk sergeant again in civilian clothes. After letting Adam into the building he lost his job and is upset with Adam. Again, you’re not forced to fight. You can try to calm down the enraged desk sergeant with words.
