In a recent article on methods for assessing artificial intelligence (AI) systems for consciousness, we argued that computational properties of internal processing should be used as indicators [1]. Commenting on our proposal, Pennartz argues that this method ‘should be supplemented with behavioural-cognitive methods’ (p. 1) because there is no consensus theory of consciousness [2]. We agree that the lack of a consensus theory of consciousness makes it more important to use every available source of evidence, but in our article, we preferred internal over behavioural assessments on the grounds that the latter can be ‘gamed’ by AI systems.
