comment Can a biological entity be thought as a simple algorithm? Case-study with the concept of randomness
Also, an interesting note about multiple realizability. What I call 'degeneracy' in my answer is the observable analog of multiple relizability, but pertaining to function. If you believe mind is a functional result (as is typical of monism and physicalism) then degeneracy is multiple realizability.

comment Can a biological entity be thought as a simple algorithm? Case-study with the concept of randomness
I've edited my answer to make my ontology clearer so your first reference to my post is inconsistent now. My issue with life being reduced to just algorithms is more because I favor the dynamical systems view of continuous evolution of states (and that how humans break such processes into algorithmic steps is a more about human ontology than nature). My ontology views life, inevitably, as a very complicated classical physics problem. Algorithms would be an emergent property of living things (and other physical processes) as opposed to what life is reduced to.

comment What does it mean to overthink?
The phrase over thinking is generally used when somebody contrives a complicated theory to explain something that can already be explained with knowledge common to all parties involved.

comment Neurotransmitter control via biofeedback?
Neurotransmitter levels are determined by metabolic processes and demand. Humans control whole systems of their body, not individual cells or molecules, so the original thread you linked is, as far as I know, as close as you're going to get. But there, you'd be controlling the whole system and neurotransmitter levels would just be a consequence.

comment How much information does the somatosensory system produce?
I see. The number of bits is equal to N, the number of binary questions asked to locate a point on a partition. So you could just keep breaking your continuous variable up into smaller partitions and asking if your point is inside of it and then your resolution is equal to the number of partitions (which represents the number of questions). But how would this tell you how much information is "being produced"? The Kolmogorov-Sinai entropy is a direct measurement of information production. The units are generally entorpy/time, but I think you can conceive them as bits if using partitions.

comment How much information does the somatosensory system produce?
Scholarpedia discusses when it's appropriate to use bits (for yes/no questions) and the error associated with not doing it. I work with dynamical systems and presume deterministic mechanisms in my systems, so I think I'd go with Kolmogorov Entropy. But the nature of the question would still be an important consideration. My tendency is to assume things exist more on a spectrum than binary yes/no, but I'm sure there are simplifying cases.

comment How much information does the somatosensory system produce?
It would depend on the model and the question being asked and the definition of information and what you hope to get with that definition.

comment Why do people make rants on Meta Stack Exchange sites?
speculation: negativity is more typical on the internet in general, because we don't get the vocal and facial feedback from our audience that we would in a live setting. Negative comments probably still come up in person, but they don't (as often) develop into a rant.

comment What is the neurobiological basis of Spearman general factor of intelligence?
imo, intelligence is an ill-defined term. I think it would take volumes to answer the question as is. Narrowing it down might be productive.
