text: uncertainty about one’s estimated state. This means that active 
  inference agents tend to avoid ambiguous states, encompass- 
  ing the avoidance of ambiguous places where self-localization is 
  challenging, ambiguous social situations where safety is uncer- 
  tain, and ambiguous bodily states, such as unsure feelings of 
  fatigue. However, one apparent exception to this aversion to ambi- 
  guity arises when exploring novel states implies the opportunity 
  to learn new things and enhance one’s model; see Friston et al. 
  (2017) for a discussion. Furthermore, and importantly, active infer- 
  ence agents will actively operate in the environment to reduce 
  their ambiguity; for example, by actively seeking informative sen- 
  sations that disambiguate in which location they are (e.g. by 
  looking for traffic signs), whether their social context is safe 
  or unsafe (e.g. by trying to understand other’s intentions from 
  their facial expressions and actions), or whether they are cur- 
  rently fatigued (e.g. by putting attention to one’s heart), happy, 
  or sad.
