Is there any way to avoid stress among team members? I mean the kind of stress that actually produces arguments and quarrels.

And what about each personality? That certainly has something to do as well, and not just tension among team members or the abnormality of a situation.

Yes, of course; choosing the members of a team is a delicate job. Look at the way in which astronaut and cosmonaut crews are selected.

What about nuclear submarines and isolated bases in Antarctica, Greenland, Alaska and so on?

For every specific situation there are also specific requirements to be met: a sailor or officer assigned to a submarine shares some characteristics with researchers that go on extended tours on isolated bases, but there are differences.

One of the most obvious is that while the submarine fighter knows that he has to stay there and fight no matter what, even if a nuclear war comes into existence, the researcher or scientists knows that he or she will return to a safe homecoming.

Naturally, submarines constitute combat environments under military law, even at peace. Research facilities are not, so people on both of them are indeed different.

Of course, even within the same environment and with people with a similar background there will be differences: Japanese submarines during WWII were arguably even better than those that the Germans had, and much better than U.S. made ones. For instance, the Japanese vessels had a much longer range - capable of reaching the Californian coast in a no-stop hop -, were faster and were better armed. Some even had aircraft.

Japanese and U.S. sailors were of course, doing a similar job and found themselves within a similarly stressing environment, but despite the competitive advantages that the Japanese had with their better submarines, living conditions inside were so appalling that morale always sunk to the botom of the sea with each prolongued and risky tour of duty.

U.S. sailors had better food, better beds, clothing, at least some sort of entertainment and they knew that they had some hope of rescue if something wrong happened. The Japanese hd none of those luxuries and nothing forward to look for; they just received punishment for their mistakes and the only thing that they could hope is to stay alive and return home sometime in the future. That´s the same problem that the Spartans had with their rigurous discipline; they could only expect to sink in their social status, but never rise, never become leaders or rich people. They both just expected to survive, period.

Moreover: as the tide of war turned against Japan, even the most loyal fighters could not afford to ingore the fact that they were becoming more probable targets for their enemies. So in the end, the efficiency of the otherwise very well trained Japanese crews with they advanced ships was lower than that of the submarine forces of the United States, the UK and so on.

Thus, no disciplinary regime, no matter how strongly embedded, culturally speaking, is enough to guarantee success. There are traits that are universal, and one is the dislike for needless authoritarianism and hopeless isolation. Under difficult circumstances people must be able to look forward to the future. .

Modern society seems to be very keen in producing stress. It seems that our way of life is designed to actually generate it. Why do we persist in such habits? It goes beyond me.

Just relax...
