Quote as: Tozzi A. 2019. The myth of falsifiability in the assessment of scientific theories. (electronic response to: Bellmund JLS, Gärdenfors P, Moser1EI, Doeller CF. 2018. Navigating cognition: Spatial codes for human thinking. Science, 362(6415):eaat6766. DOI: 10.1126/science.aat6766.
It has been stated that "a founding principle in science is the ability to falsify your theory". This logical, Popperian tenet, dating back to the first half of the 20th Century, has been fully discarded, in particular by Lakatos, and then by Sokal, Bartley III, and so on.
A scientific theory does not need to be falsifiable, rather simply requires experimentally testable, quantifiable previsions that must be treated with statistic methods to evaluate their probability.
To give an example related to the scientific (not philosophical!) theory of the multidimensional brain, the "geometric codes that map information domains" can be tested by looking at the required hidden symmetries, possibly endowed in the real neurodata provided by currently-available techniques, such as EEG, fMRI.
