There was quite an interesting discussion a few weeks ago on Free Will

One point made by Hemidactylus that didn't get developed any further

making a decision - he gave the example of buying a car. It's also
common for someone to want to "sleep it on it" before making a
decision where the decision is important but it is not clear what
decision is best. If a decision is essentially predetermined then what
is the point of that time and effort or sleeping on it?

Do you not see that this argument depends on the belief that there was
an *option* to make the decision earlier under different conditions
(lack of 'thinking it over' and/or 'sleeping on it'). IOW that free will
exists. You are 'begging the question'.

It's actually the complete opposite, I am starting with the assumption
that there is no free will and asking what then is the point in
deliberating over the various options. You seem to be taking things a
bit further and saying that if determinism exists then there aren't
any options to begin with but that is just a variation in emphasis, it
doesn't address the question of why we spend so much time pondering
those options when they don't even exist.

You missed his point.
Consider writing an algorithm controlling a robot walking down a path.
The robot comes to a fork in the road. Does it take the left fork or
the right fork?

The robot has no free will. It can, however, process data.

The algorithm can have layered complexity. Scan left, scan right,
process data. Simple-minded algorithm scans 1 sec each way, sums up
some score of positive and negatives and picks the best. If it's a
tie, it might kick the random number generator into gear.

Alternatively, it can get into a loop where it keeps scanning left
and right until one "choice" passes a threshold for "better" that
is not just a greater than sign, maybe 10% better or such. From
the outside, this is "pause to think". With a little imagination,
one can add much more complexity and sophistication into how the
robot chooses. It can be dynamically adjusting the thresholds. It
can use it's wifi connection to seek external data. It can find that
its wifi signal is poor at the fork in the road so back up to where
it was better.

Map "go home and sleep on it" to some of that or to variants.
Map it into Don's words. The robot could not "choose" left or
right until its algorithm met the decision threshold, i.e. it
didn't have a legitimate option yet. (hopefully he'll correct
me if I have abused his intent too far)

To an outside observer lacking full knowledge of the algorithm,
it looked like it had a choice but inexplicably hesitated.

 
It is *you* who have missed the point. What you have described above
is an algorithm to process data and arrive at a decision; what I was
asking about is why we delay once all the information that is
available or likely to be available *has been processed*. Once all the
information has been input in your algorithm there is no reason for
the processor to continue analysing unless you add in some sort of
rather pointless "just hang about for a while" function; no matter how
many times your algorithm runs with a given set of inputs, it will
reach the same decision.

>
The answer to that is simple: Once all information is in, it has *not*
all been processed. The decider may have thought about price, quality,
ease of cleaning, subjective appreciation of pattern (for both self and
one or two others), and availability, but there are undoubtedly
tradeoffs midst all that data that cannot be expressed in six-variable
differential equation, much less in something that you could decide by
reasoning. Furthermore, there are innumerable other factors that the
decider probably did not consider on the first pass (how does it look in
various other lightings? What, if anything, would it imply about our
social status? Is it going to remind me of Aunt Agatha's horrible
kitchen?) All of that processing takes time,

Which goes back to the question I have already asked here about the
underlying principle of Cost versus Benefit in Natural Selection; if
the benefits from a trait or characteristic outweigh its cost, then
that trait Is likely to be selected for; if the cost outweighs the
benefits, then it will likely be selected against; if cost and benefit
more or less balance out, then it is really down to chance whether or
not the trait well survive.

What you have said above highlights that there is significant cost
involved in this pondering in terms of brain resources. Can you
identify any benefits that would outweigh the cost of such pondering
when the final decision is predetermined?

and since it is way too
complex to do consciously, the processing (probably) works best when the
brain is otherwise at rest.

Are you seriously suggesting that the brain is at rest when we are
sleeping?

>

One exception to that is your suggestion of a
random number generator when the two options look more or less equal
but your problem is that that randomness is very antithesis of
determinism.

>
I don't think that's true. A process can be both random and determined.
But that hinges on definitions of random, and is outside my area of
competence.

Sorry, I don't even know what you mean by that.
