These aren't illusions, even free will; let alone time, money and probability.
Free will concept (as used by anyone but philosophers) makes sense; there are things that are controlled by your conscious processes. For example, now I'm deliberately controlling my arms to type this comment, isn't it a free will? Of course, I'm entity within physics, my thoughts and actions are fully determined by physics laws (whether random or not), etc, etc. Yet, I can deliberately move my arm.
Probability isn't an illusion; probability is a measure of uncertainty, and probability theory is a large and very useful field mathematics which supplies us with knowledge about how to use such a nice tool. It's not an illusion; it's a mathematical concept.
Time isn't an illusion; no matter how timeless your physics theory, it must contain explanation for phenomena that you now call time. If you develop a shiny new gravitation theory, apples won't fall differently. You can a new shiny timeless physics, butwhatever you now call time isn't going to disappear. It would be explained as a dimension, or as a function of position of all particles in the universe.
As for money, I don't quite understand why they are considered an illusion at all. I have checked banknotes in my wallet; they are real, as far as I can tell. Did you mean some economical misconceptions?
The concept is that by aggregating things we observe that form parts of processes, or physical things, sometimes we end up calling them one name, or feeling them as one thing as a category or a concept.
For example, if we see a sequence of events where the first gave way to the second, which gave way to the third, fourth, etc. all the way to the 10th, because each one was not possible unless the previous one had happened we tend to "feel" as if something is passing, so we feel time, and we call it time, and create methods for measurement, and it a...
After I posted my great idea that "Determinism Is Just A Special Case Of Randomness" because "if not I don't see how there could be free will in a deterministic universe" I was positively guided by the LW community to read the Free Will Sequence so I am learning more about our biases and how we build illusions like free will and randomness in our minds.
But I don't see a list on LW or Wikipedia of a list of cognitive illusions and I think it would be great to have one of those just as it is useful for many people to visit the List Of Cognitive Biases page as a study reference or even to use in day to day life.
I think these are some cognitive illusions that are normally discussed as such:
- Free will
- Randomness/probability
- Time
- Money
There must be many more, but I don't find a list with summaries and that would great (to help me avoid writing posts like my "great idea" above!).
EDIT: The majority of comments below are about questioning if they are illusions or not and if they should be called cognitive illusions.
I guess there is no list of cognitive illusions because there is no academic agreement about these issues like in cognitive biases which are generally accepted as such!
Thx for the comments!
