Germans trust authority far, far more than Italians or other Mediterranean people do. They assume that, if something is determined to be safe, it is because people who know what they’re doing thoroughly checked the situation and made this determination accurately. If in Italy something dangerous happened in a lab and then someone came out and was like “No problem! You can come back in everything’s fine!” We’d all be like
Yea right! We’re going home. For the rest of the week.
Our people just don’t trust people in authority with anything. Many would say with good reason, but it is the one time that you will find an Italian who is more cautious than a German.
Oh sweet irony, how you make life fun!
