Still, intuitive assumptions about behavior is only the starting point of systematic analysis, for alone they do not yield many interesting implications.

Summary

This quote suggests that while intuitive assumptions about human behavior are a good starting point, they are not enough to generate meaningful insights. Systematic analysis is required to dive deeper and uncover interesting implications. This implies that simply relying on our instincts or initial beliefs may limit our understanding, and that a more analytical approach is necessary to explore behavior and its consequences more fully.
