I know there are probably many different reasons, but what do you think is the main reason or most common one?

The most common reason is complacency. The same old thing. Oh, you will hear that it is because they didn't get any attention and crap like that, but that is a lie. It all boils down to getting some "strange" stuff.

I believe emotional age/experience is much more important.  However that being said, if you 'go too far' outside your generation, you can later learn that you didn't have as much in common as you thought.. generational issues can be biggies.. it's to each their own and what they prefer/workout.

Fear is the main reason. People fear what they can't understand, most people don't reach out to anyone outside their inner "circle" of friends, their comfort zones. Fear keeps them from loving others the way they should and this is one of the reasons why we're in the mess we're in. \n\nIf we all worked together to better the world, it would be an outcome so awesome, there's no words to describe what our world would be like.\n\nUpbringing is another thing. I was raised a certain way, but I broke out of that mold because I wanted to be ME and not some carbon copy of what they wanted me to be. I love people, not their skin color, I never see color, I only see the person!!

I believe there are many reasons.\nLaziness is the main one.  Paul had to deal with it when he taught...he basically said, "Do I have to keep going over the same old thing you thick headded people?"\n\nAnother reason is that God has gifted a few of us to teach.  I believe it is the people that have a hunger for his word that he raises up to begin teaching others.  Not everyone has that hunger.  If everyone did, they wouldn't need teachers.\n\nTake your question and flip it around into a praise.  Thank God that He has given you a hunger and you dig into his word...  Now, use it to teach others.\n\nEphes. 4:11-16 (NKJV)  \n    And He Himself gave some to be apostles, some prophets, some evangelists, and some pastors and teachers, [12] for the equipping of the saints for the work of ministry, for the edifying of the body of Christ, [13] till we all come to the unity of the faith and of the knowledge of the Son of God, to a perfect man, to the measure of the stature of the fullness of Christ; [14] that we should no longer be children, tossed to and fro and carried about with every wind of doctrine, by the trickery of men, in the cunning craftiness of deceitful plotting, [15] but, speaking the truth in love, may grow up in all things into Him who is the head--Christ-- [16] from whom the whole body, joined and knit together by what every joint supplies, according to the effective working by which every part does its share, causes growth of the body for the edifying of itself in love.

I'm struggling to come up with a GOOD reason, just plenty of BAD ones:\nGreed, fear, pride, resources, laziness, not enough money.

One of the simpler reasons is personal choice. The majority of people prefer to associate with people that are similar to them. This is basic group dynamics. We gravitate toward people with whom we have common interests.

I'm curious about this question too... and if you could explain your answer using examples why you think what you think?

both i'd have to say. The reason will always be over something... usually irrational considering the reasons behind them.

Why choose?  Why not both of them?

A common question?  Why do you want to know that?

It saves on the cost of vanadlism. Seriously. Because it's a place of worship and well. Some people just can't help themselves. \n\nThere are other reasons as well, but I don't know them.

Nationalism....everyone had a heightend sense of pride in their own nation. It would be easier to bring up soliders for the "great war" since everyone believed their nation to be best and worth fighting for. Also like nations got into alliances and often these alliances got quite tangled and would eventually be seenas probably the one of the main causes for the war. Imperalism....the powers that be in Europe were all competing on the international level for resources, markets, and prestige. The highly hostile and competitive atmosphere because of conflicting interests helped add to a war climate. Militarism... since most of the main powers needed a strong military to be able to exert their imperial dominance, strong militaries were popular during the period. As one nation built up their arms, the others would follow suit in order to avoid the balance of power from tipping to far one way. Each of these causes helped build a foundation for war which was sparked because of the archdukes assination.

Good question. I think it's because people assume that common sense should be enough. However, the trends pointing toward greater stress at the workplace (even psychological illnesses), suboptimal productivity, etc. show that there is a need for O.B. (or at least, for managers to understand more about O.B.).\n\nCommon sense is good, but unfortunately, when things break down, we need expertise. It's true in so many spheres of life. Healthy dieting is common sense, yet we need doctors. Taking care of one's teeth is common sense, yet we need dentists.\n\nAny expert discipline, including O.B., is valuable once things break down and we have to analyze them technically to find the cause of the dysfunction.

-.- and you wana know why?

I think the biggest issue is poverty.  It also affects everyone everyday.  A lot of the healthcare problems are because of it.  People who are not poor are paying for the people who are.

some cause cost, some contribute. \nmuch like the "legal" population.\nstatistics can be deceiving and usually do just that.

The main reason is to get better results.
