Many of the judgments we make daily, although they may seem sensible to us, are, in fact, far from rational and can lead us to make bad decisions. These erroneous judgments are called cognitive biases, and some 250 different ones are known to date. While the teaching profession encourages the development of critical thinking skills, the learner-teacher relationship is nevertheless conducive to the development of some of these biases, and they can have a significant impact on learning.

We are all quite familiar with the phenomenon of optical illusions, but less so with the phenomenon of cognitive biases. However, these perceptual distortions that are to our mind what optical illusions are to our visual system lead us to make wrong judgments or bad decisions daily

A sub-domain of machine learning – itself a sub-domain of AI – deep learning is also its most advanced form. It allows Big Data to be processed using artificial neural networks inspired by the neural network of the human brain.

We may all "know" what humour is, but when we look at it more seriously, we realize that it is far from simple. Its mechanics, unlike that of laughter, can be challenging to dismantle from a scientific point of view.

Most of us have experienced all four modes of learning in our lives. Our ability or preference for one of them may depend on our personal disposition, the accessibility or organization of these modes of learning, or the type of learning involved
