# Evidence either implicitly or explicitly involves a critical path [[Projects need to build narratives of perceived progress on top of pieces of evidence]]. Narratives are just causality stories — in high uncertainty situations narratives are how we connect inputs and outputs. [[Narratives are how we deal with uncertainty]]. In other words, the narratives are imagined [[Critical path]]. When a project leader is presenting evidence for the trajectory in their narrative, that evidence is either implicitly or explicitly fitting into a critical path. ### Related * [[Definite optimism requires both a vision and evidence that we are on a trajectory to reach it]] * [[Elon is able to both draw the beginning of the trajectory and the dotted line]] * [[Program design could be done as a residence program]] * [[raoGUTSGrandUnified2018]] [Web URL for this note](http://notes.benjaminreinhardt.com/Evidence+either+implicitly+or+explicitly+involves+a+critical+path) [Comment on this note](http://via.hypothes.is/http://notes.benjaminreinhardt.com/Evidence+either+implicitly+or+explicitly+involves+a+critical+path)
