her offspring. We have $$\Gamma = \begin{pmatrix}1&0.1\\s&1-s\end{pmatrix}.$$

-   We consider now the relationship between two students and their professor. Because of her status, the professor has a high influence on her students, while being very little influenced by them. Assuming that the relationship between the students is symmetric, we have $$\Gamma = \begin{pmatrix}1&0.1&0.1\\1&0.2&0.2\\1&0.2&0.2\end{pmatrix}.$$

Likelihood landscape
--------------------

In our model, some conceptualizations (i.e. knowledge-like functions) appropriately reflect the structure of the world, while other do not. For instance, in an environment in which blue berries are safe to eat while green berries are unsafe, color categorizations that discriminate between blue and green are superior because they appropriately capture the structure of the environment. Individuals don’t know *a priori* how to categorize their environment. An individual who, by chance, only ever ate blue/safe berries might consider that discriminating between blue and green makes no sense. Yet, an individual who got sick after eating green/unsafe berries is likely to refine her color conceptualization to avoid being sick again. Sometimes, alternative and irreconcilable conceptualizations are equally likely. As an illustration let us consider the shape illustrated in figure \[fig:cup\_or\_faces\]. One might consider that it represents (1) two faces (in black) or (2) one cup
