Introduction to rating scales

Can attitudes, feelings and emotions be transformed to numbers?

You are using a specific empirical-atomistic epistemological approach labelled positivism when you measure and analyze attitudes, feelings and emotions using quantitative methods (numbers). Representatives for the human sciences raised criticism around the early 20th century towards the practice of turning subjective phenomenons like attitudes, feelings and emotions into objective numbers and statistics. They argued that research on people’s attitudes, cultural and social life works according to other principles and are not accessible using the positivistic approach. This is a debate that is still alive and it might be a good idea to be aware of this.
