In this paper first I introduce curation and affordance in chance discovery. According to Matsumura's definition, a shikake is a trigger to start a certain action or to change person's mind and behaviour. As a result of the action, all or part of problem will be solved. A chance and shikake are in a certain sense similar. In addition, affrodance seems to play a significant role in shikakeology. From the point I will discuss the relationships between chance discovery and Shikakeology.
