A trick to help grow a potentially subversive idea in people's heads: connect 9 out of 10 dots but leave the last unconnected.

People see a dangling dot and want to connect it, and they are drawn in.

Leaving one dot unconnected allows other people to co-create meaning.

When people co-create, they feel an ownership, they are drawn in.

The "leaving a dot unconnected" is similar to the "leave a simple TODO to do in the morning to get sucked back into the flow of programming" trick.

When telling a story, the indirectness allows the listener to extract something different than the literal message, leaving a dot unconnected.

The safe subversive tone: put the spicy stuff exclusively between the lines.

Make the reader work for it to extract the spicy stuff.
