Why Do People Favor Family?

Your brother asks to borrow money and you lend it without a contract. A coworker asks for the same sum on the same day, and you reach for terms, a record, a date of repayment. You have never examined why the two requests feel so different. You only know that they do.

This lesson explains the pull toward your own blood: where it comes from, why it follows a gradient from the nearest relative outward, and why it governs conduct that no one ever taught you. You will leave able to map the circles of trust that shape your own cooperation, and to see why trust between strangers must be built from materials that family supplies for free.

The full account, including what civilization had to invent to replace the bond that kinship furnishes on its own, lives inside the course.
