You know I have thought about this for a very long time and engaged in some deep analysis of the thought processes of my friends, acquaintances, and professional colleagues who are liberals and the conclusion I have reached is the following (sorry for the length...it's necessary unfortunately):
Liberals tend to be very micro-focused people. That doesn't mean small minded (that's a different argument

), it means their point of view is such that little things bother them more than big things. They are very good at identifying individual elements of an issue and creating quick, simple solutions that will effectively address that individual point. However, their focus on the small means they have a very bad habit of missing the big picture and understanding that changing one thing will force other things to change in order to compensate is usually beyond their natural comprehension level. They really have to work hard to understand that.
As they are more idealistic and optimistic, they tend to focus on "how things should be" instead of "how things are". That's great when an issue can be addressed in a vacuum because it offers the chance for true development of culture and humanity. However, as things can very rarely be addressed in a vacuum, reality tends to get in their way in a very frustrating and persistent manner.
They are usually very offensive minded and quick to action and experts at short-term strategy. In a game of chess for example they are more likely to use 2-3 pieces on a frontal assault right out of the gates while ignoring the development of any real pawn structure for defense. If their initial attack is effective they win. If not they are a sitting duck once their offensive is beaten back.
So what happens with liberals is they see one thing that is out of balance or seems to them to be unfair and it galls the living shit out of them. As they are offensive minded, quick actors they immediately jump into addressing the problem. They quickly create and implement an effective solution. However, as the big picture is beyond them they step back to look at the result and realize that their actions have cause reaction somewhere else and now something else is out of whack. So in the end the result is that they run around in circles putting out fires of their own creation.
Now for the Republican mind it's really the exact opposite. We tend to be macro-focused. It's the big picture that concerns us more. We don't mind if a few little elements are a little out of whack so long as the overall balance is maintained. We excel at understanding how taking action to address A will force B to change to compensate and that will in turn mean C will change and D and on down the line. As such we are experts in long-term strategy and creating solutions to problems that address an issue in a such a way that the effect on other things is reduced. However, our focus on the large means we tend to miss the subtle nuances of specific situations and probably don't appreciate enough how out of balance an individual issue might be when placed side by side with a small number of similar issues. Our focus is on everything as a whole.
We tend to be defensive minded and strategic planners. In a game of chess we will meticulously set up an impenetrable defensive line with pawns and multiple pieces and force our opponent beat himself to death against the brick wall we have established. But that takes time to develop and that means we are slow to show attacking force. As such, if we have the time to get our defense set up we will win the game. If we are forced to attack before we're ready or our defense can be disrupted while we are still developing it, then we're in big trouble.
We tend to more realistic and pessimistic so when a liberal starts talking about "how things should be" we tend to say "sounds great but it's impossible to establish because all this other stuff will have to change as a result and it will create a cluster **** in the grand scheme." Usually we're right but that also means that we have a habit of leaving things alone which really do require attention.
So for us, when something is out of whack, we look at the issue, examine it with a microscope, consider every little possible effect on every little possible action, develop far reaching, complicated strategies and implement them. Usually it works out better, but it takes us *******
forever to do it because we spend an eternity analyzing it. That means that development and advancement of culture and humanity comes slower with the macro-focused Republicans.
Take some time and watch the news. Listen closely to what Democrats say and what the Republicans argue. It's an interesting exercise to watch FOX News and MSNBC back to back and listen closely for the difference in micro-focus and macro-focus when it comes to policy ideas and strategy and what each party defines as a "problem".
Think of the Obamacare. Remember the Democrats saying "just pass it and we'll fix it later"? Well there you go. Micro-focused, offensive minded, quick to act, running around putting out fires of their own creation. Remember the Republicans saying "if you do this you're going to **** up a whole bunch of shit over here and over there"? Well there you go. Macro-focused, defensive minded, slow to act, maintain the overall balance.
Is it any wonder why we don't get along? The Democrats keep ******* up the balance and creating more shit that needs to be fixed, and the Republicans won't get off their ass and take action because we're too busy thinking about it.
In my opinion this nation would be best served in regards to many (not all) things if the Democrats said "here's what we would like to accomplish" and then sat down, shut up, and let Republicans figure out a way to make it happen.
