In this case rationality is a false distortion of what is going on. Living and thinking is at a higher level that rationality. We can use computers, logic, maths and rules to improve our rational mind, but thinking is much more that rational thinking. Creativity and emotions play a vital role. Destroy emotions and you loose your memory (citation required), because memorizing is linked to attention and attention is linked to emotions and feeling.
As a mathematician I can prove a theorem and give a prove, but there is something creative in finding a proof. Sometimes our mind is a wonderful mind.
Rationality is also not the opposite of emotionality. You don’t have to be Spock to be rational.
An example: I am a rational people, I will pick certain portion of reality that allow me to construct a good model of myself, with blind eyes for the part I don't want to see.
You can use "rational thinking" to construct rationalization of your behaviour.
Since there is no logical notion of justice, rational thinking and rationalization are not far away.
If you're excluding data points because they lead you away from your desired conclusion, then you're not thinking rationally, you're rationalizing.
