text: This reflects the fact that a Dirichlet distribution with α = ( 1 , 1 , … ) {\displaystyle {\boldsymbol {\alpha }}=(1,1,\ldots )} has a completely flat shape — essentially, a uniform distribution over the simplex of possible values of p. Logically, a flat distribution of this sort represents total ignorance, corresponding to no observations of any sort.
