Diferentes tipos de decisões e um experimento sobre a geração inconsciente de decisões livres: uma análise conceitual

Philosophical issues such as free will and the role of consciousness in human action have become a topic of interest to neuroscience. While this contribution is of great value to extend our knowledge on these issues, the lack of clarity about the concepts being investigated may interfere with the interpretation of the relevant results. An interesting experiment (Bode et al ., 2011) that investigates whether decisions are generated consciously or unconsciously suggests a conclusion about whether human beings decide freely. These issues are considered relevant philosophical issues, but the experiment lacks conceptual precision, and this weighs on the interpretations of data and results. I argue that further conceptual analysis of decisions shows that the experiment investigates one kind of decision, while it unwarrantedly draws conclusions about human decisions in general. A better understanding of what is considered to be a decision helps clarify to which extent the results show that decisions are generated unconsciously. This shows that conceptual precision is crucial for research on the area as well as methodological rigor. Keywords: decision, intention, consciousness, brain activity.
