 Hope et al. (2013) have argued that individuals with anorexia are in the grip of affective states that shape how they see the world. Yet, although the world presents to them as one way, they may at another more reflective level, reject the appearances. Thus an individual may have a strong feeling or emotional sense that she is fat. But even though these feelings incline her to accept the proposition that she is fat she may not in fact believe at a higher level that she is fat. She may know quite well that she is dangerously thin. An analogy here with optical illusions is helpful. The experience of seeing a stick in water as bent is incredibly powerful, but we may nonetheless know it is not bent. However, the mental state that is most authoritative when it comes to reporting our beliefs may not be the same as the mental state that is most motivationally powerful. When it comes time to make choices about treatment, the salience of the affective phenomena and the relative lack of salience of the dangers of self-starvation may lead a person to refuse treatment.
