Does intelligence have a point of diminishing returns in evolution?

In summary, some people believe that intelligence does not play a role in happiness, while other believe that the more aware and knowledgeable a person becomes, the less content and depressed they can feel.

Are intelligent people really happier than less intelligent people? Some people are less aware and more oblivious to what goes on around them and seem quite content with it and living happy lives even though they don't seem to realize or care who or what they perhaps unintentionally hurt. Would more socially and environmentally aware people be happier if they weren't? As they say, ignorance is bliss. I think I was happier as a child when I was less aware of the realities of things and how the world really is.

Maybe I seem to worry too much. Maybe I try to use reason so much instead of how I feel naturally. Like if I feel a certain way, I question why I feel that and if that is the right way for the better of mankind instead of usually just doing. I seem to stall to much by thinking about the action before hand unless of course, impulsiveness overwhelms me.

I'm not saying I'm intelligent. Maybe it's a chemical imbalance. But sometimes I wish I could be dumber like some people and not be aware or even give a crap about what happens to the future of mankind or our environment. Is there a point of diminishing returns for intelligence with regard to evolution just as there is with lots of other traits?

Is there a point where someone is so intelligent that they prosper, maybe being the CEO of a company but not caring if that company hurts the future of mankind? While a more intelligent man is smart enough to know that money is not everything and that being popular and rich will not train him or his offspring for the real world by being spoiled. Maybe you get what I'm saying and maybe you don't. Maybe I'm ignorant in thinking learning more and more leaves you with less and less surprises in the world that it becomes mundane. It's just been my experience.

I don't think this concerns evolution at all. This is more an existentialist issue.

I would say that at first you don't know what you don't know, but then you learn a little and you come to know what you don't know, and that point it feels a little depressing, but then you learn a whole lot more and the world starts to make sense and then I don't think it is depressing anymore.

If the depression comes from the apparent meaningless of it all, learning more can show you that the world had to come out this way, given what it was in the past. There is reason in how people have turned out, and it is unfortunate that we typically can't see it. If we are cogs in a machine, most of us are oblivious to the machine. This has nothing to do with religion, I don't mean that this social machine has some purpose.

I just think you should continue to learn, especially about the why of things. Knowledge is the way to understanding, and the search is its own reward.

This question takes place at the heart of the underlying meaning of "Intelligence". Therefore all depends of what you understand for an intelligent person.

Trying to clarify this issue, let's take a look at the Free Dictionary:
In·tel·li·gence
a. The capacity to acquire and apply knowledge.
b. The faculty of thought and reason.
c. Superior powers of mind.

In my opinion all these meanings are in no way involved with the "ability" of being happy or unhappy.

Even if for an intelligent person we think of someone really mature, who knows about life and who is able to handle the sorrow, we must take account that happiness is a complex and vague term. Quoting http://en.wikipedia.org/wiki/Happiness" :
Happiness is an emotional or affective state that is characterized by feelings of enjoyment and satisfaction. [...] While a person's overall happiness is not objectively measurable, this does not mean it does not have a real physiological component. [...] Philosophers observe that short-term gratification, while briefly generating happiness, often requires a trade-off with negative repercussions in the long run. Examples of this could be said to include developing technology and equipment that makes life easier but over time ends up harming the environment, causing illness or wasting financial or other resources. Various branches of philosophy, as well as some religious movements, suggest that "true" happiness only exists if it has no long-term detrimental effects. [...]

So I guess the short answer to your question is: No. The fact of being more aware of what happens in your environment seems to be more a question of sensitiveness and attitude rather than intelligence.

In my opinion, there's no such thing as 'thinking too much.' The only time thinking becomes a negative is when it turns into delusional thinking i.e. conspiracy theorists. Rational thinking on the other hand is always a positive. I've heard this argument before from people I know about impulses and feelings being more important than reasoning and thinking, however I don't buy this one bit. Sure, feelings and sensation are what makes us animals and more specifically, human. But as humans we were blessed with reasoning, thinking, and memory. We can learn from our history unlike any other species living on this planet. And to say you've learned so much that the world becomes mundane is rather depressing. Knowledge is infinite, and I don't think we've even reached the first whole number yet if we're looking at knowledge on a number scale. And even if we have, we're still not any closer to infinite than we were when we were at zero.

Why to exist when there is no outcome...
Why to live when we are just going to die & become a nonexistent...
Why...

I usually have these questions in my mind, But the answers are infinite which are all hypothetical & no satisfying answer is found.

WE are the ones who make our surrounding environment, which involves happiness and sorrows... which just have no impact on what's going to happen next...

I say that because I don't believe in free will, To give a simple reason; I am writing this post because you had previously started the thread, You started the thread due to what you were thinking about, You were thinking on this issue due to some reason, that reason had another reason and so on... An infinite string of events is what you get. If the reason for the reason of the other reason of another reason (which can even conclude to the main point where existence began) had never occurred I wouldn't be writing this post now.

As an answer to what you are talking about, No matter if someone is intelligent or not, Happy or sad, sensitive or not, Whats going to happen will happen, as a natural reaction to this infinitely long string of events.

This is just what I have concluded due to whatever I have experienced in my life, Maybe true maybe not but what I like about this string is that I've always observed as being concious, What ever happened to me even if it was a horrible disaster for me, It had good effects in my life in the long distant future.

I'll be glad to know your comments...

^ RE: "why to exist"

Well, for one, you seem to enjoy discussing philosophy and hearing what others have to say. So, enjoyment seems like a reason.

Interesting comment about free will. Realistically, though, I don't think what you're thinking about is will at all. I think it's more an observation of cause-and-effect relationships. So I'd have to ask, what do you think free will is?

Well, I don't really think that enjoyment is a sufficient reason, Simply what's the reason for enjoyment... If you just start it you'll get a complete string which once again leads to an infinite number of why questions & as long as we are not sufficiently knowledged about the universe, I don't really understand the way to answer this question...
But excellent work in figuring out :" you seem to enjoy discussing philosophy and hearing what others have to say" that's absolutely true :biggrin:

As far as the definition of free will is concerned, I'll have to say its different from person to person... Each person defines it upto a certain extend & this is what makes different people to have different opinions on the topic... To me it's exactly what determinism suggests, & I believe the the will is a Consequence of the events taken place in past. As you mentioned, cause-and-effect relationships are directly dependent to the topic of free will...

^ What I meant is that I see cause-and-effect as something completely distinct from free will.

I believe they are separate because we cannot determine the effects of an action with 100% certainty. This is why you cannot plot out the chain of any of your future actions.

If you think your existence is pointless, and the indulgement of learning science and speaking about philosophy and general enjoyment is not enough to make you content, then why do you continue to exist?

It doesn't make sense to ask why one should live when he or she knows he or she will eventually die, when there is at least part of the answer all around you.

Why shouldn't we be able to do so? Why not predict everything with 100% certainity?
If you are talking about Heisenberg's principle of uncertainity or Quantum mechanics, let's not forget the 'Hidden Variable Theories' which were first proposed by Einstein & later developed to EPR paradox which entails that beneath the probabilities of quantum mechanics there are fixed variables.

Even if we look at the researches done by a different number of biologists, But to me Benjamin Libet's work & its outcomes are really interesting;

(This is a quote from wikipedia.com)
A seminal experiment in this field was conducted by Benjamin Libet in the 1980s, in which he asked each subject to choose a random moment to flick her wrist while he measured the associated activity in her brain (in particular, the build-up of electrical signal called the readiness potential). Although it was well known that the readiness potential preceded the physical action, Libet asked whether the readiness potential corresponded to the felt intention to move. To determine when the subject felt the intention to move, he asked her to watch the second hand of a clock and report its position when she felt that she had the conscious will to move.

Libet found that the unconscious brain activity leading up to the conscious decision by the subject to flick his or her wrist began approximately half a second before the subject consciously felt that she had decided to move. Libet's findings suggest that decisions made by a subject are first being made on a subconscious level and only afterward being translated into a "conscious decision", and that the subject's belief that it occurred at the behest of her will was only due to her retrospective perspective on the event.

Later Ammon & Gandevia found out that neurostimulations could effect the outcomes

Ammon and Gandevia found that it was possible to influence which hand people move by stimulating frontal regions that are involved in movement planning using transcranial magnetic stimulation in either the left or right hemisphere of the brain.[63] Right-handed people would normally choose to move their right hand 60% of the time, but when the right hemisphere was stimulated they would instead choose their left hand 80% of the time (recall that the right hemisphere of the brain is responsible for the left side of the body, and the left hemisphere for the right). Despite the external influence on their decision-making, the subjects continued to report that they believed their choice of hand had been made freely. In a follow-up experiment, Alvaro Pascual-Leone and colleagues found similar results, but also noted that the transcranial magnetic stimulation must occur within 200 milliseconds, consistent with the time-course derived from the Libet experiments

As a result; Why can't we conclude human brain as a natural reaction calculator which uses past & present events to calculate what to do next.

There are a many other such reasonings when I look at the scientific observations with respect to my point of view...

______________________​

When it comes to the point of existence, I never said its pointless, Because if there was just no reason then what's it all about...? I do believe in a reason behind the whole of this system but to me the reason is yet far away from human understanding...

Each comunity has a specific answer to this question but non of them proved correct. Atleast upto this date.

______________________​

Maybe our concept of being dead is really wrong and it doesn't means becoming a nonexistent... Like what many of the religions suggest...

I don't have time now to read the entirety of your reply but for now:

Before we get into the ability to predict the future, let's define it.
Are you saying that you can determine down to the second what and when will occur in the future? Or just generally that some things will happen.

Upon your idea of supreme cause-and-effect we cannot predict everything with certainty because we don't have the computational abilities, and because you don't know for certain that something won't change between now and the proposed time of the event.

Just that we can't do it doesn't means its totally imposible...
Centuries ago no one could even imagine what a Black Hole is or what the singularities are...

Future is a product of past & present events combined with laws of nature...
(from my point of view)
 

1. What is the point of diminishing returns in evolution?

The point of diminishing returns in evolution refers to the point at which further increases in intelligence do not provide significant advantages in terms of survival and reproduction. In other words, there comes a point where being more intelligent does not necessarily lead to a higher likelihood of passing on genes to future generations.

2. Is intelligence the only factor that determines an organism's evolutionary success?

No, intelligence is not the only factor that determines an organism's evolutionary success. Other factors such as physical traits, environmental conditions, and social behaviors also play a role in an organism's survival and reproduction. Intelligence is just one aspect of an organism's overall fitness and may not always be the most important factor in certain environments.

3. How does natural selection affect intelligence?

Natural selection is the process by which individuals with advantageous traits are more likely to survive and reproduce, passing on those traits to future generations. In terms of intelligence, natural selection can favor individuals with higher intelligence if it provides a significant advantage in their environment. However, there may also be trade-offs where other traits are favored over intelligence.

4. Can intelligence continue to evolve indefinitely?

It is unlikely that intelligence can continue to evolve indefinitely. Evolution is a result of natural selection, and as mentioned earlier, there comes a point of diminishing returns for intelligence. Additionally, there may be limits to the brain's capacity and the resources needed to support higher levels of intelligence.

5. Is there a correlation between brain size and intelligence?

There is a general correlation between brain size and intelligence, but it is not a perfect correlation. While a larger brain may provide more potential for intelligence, the structure and organization of the brain are also important factors. Furthermore, there are exceptions to this correlation, such as some species of birds and primates with smaller brains but high levels of intelligence.
