The appeal of generality

With articles like:

• Generalised genetics;
• Generalised epidemiology;
• Generalised symbiosis;
• Universal Darwinism;
• Universal selection;
• Repology;

...to my name, readers might guess that I think that generality is a virtue in scientific theories. Why is generality a virtue?

• General theories explain a lot of facts with little theory - satisfying Occam's razor;

• Society slices science up into specialist-sized pieces. These are unevenly distributed - and much of value falls down the cracks between the theories. General, broadly-applicable theories are an attempt to compensate for this flaw.

I think that's about it. The systematic neglect of general theories by others might also be a contributing factor.
