Color Changing Card Trick

Professor Richard Wiseman has created this interesting clip to show how our mind interprets information.



Remember what we talked about in class about the input, decision, output and feedback look for skills?
Well, what if there is an error introduced in the input stage of the process?
We can see that if it is undetected, it affects the decision making phase and ultimately the output channel.
In that case, feedback cannot be accurate because what we are assessing is NOT what we think we are assessing.
