Because pure objectivity in social sciences is a myth, a utopic state at the best of times? We all have biases when it comes to deciphering human behaviour -- the best scientists will try to shed them harder than others, but they&#x27;ll likely still retain some.<p>On top of that, you have to consider that social sciences (including economics) are &quot;Schrodinger objects&quot;: as you observe and describe them, <i>they change</i>. Once you understand that, you can leverage the dynamic for personal or political gain, which is extremely common.
