+# Decision-making and new contributors
+
+This section has two aspects. The first is that everything but unanimous
+decision-making is disempowering and de-motivating (harmful). Majority rule
+(mob rule) is easily demonstrated to be so: anyone *not* in the majority
+quickly gives up in resignation, even if their contribution is critically
+important. Unanimous decision-making requires that the issue be discussed
+until it is fully understood by *all* members (or members recognise that
+they do not or cannot understand the issue, and abstain).
+
+The introduction of new contributors really requires specially spelling
+out. The last thing that is needed is for a new contributor to introduce
+changes that drain the time and resources of prior contributors to the
+point where the project fails. Unanimous decision-making ensures that
+all members (who inherently have a longer term of service to the project
+than any new member) have the right to veto proposals that disrupt the
+project. In a "mob rule" scenario, there is the potential for enough
+new members to join simultaneously that they could easily completely
+take over the project. Unanimous decision making prevents this scenario.
+
+It is also worthwhile noting on the subject of unanimous decision-making:
+its effectiveness decreases as the number of contributors goes significantly
+above around eight. If that occurs, delegate! Form sub-projects, agree
+roles and responsibilities, and go for it. Divide and conquer.
