In my conversations with agnostics I have found that most of them have little interest in gods. Most atheists will say "show me the evidence" rather than actively searching for evidence themselves, and that is also the position of most agnostics. They view the search for gods as a waste of time.
Most agnostics are "shrug" agnostics - "Eh, I don't know" (shrug). Most atheists say "Show me the evidence" so they can look up the appropriate snarly response in their Atheist Playbook. Across the whole spectrum of atheists, agnostics and believers, few have any real interest in whether what they sorta kinda believe bears any relationship to metaphysical Truth. Most people are just looking for a safe and comfortable landing spot for social, economic or other reasons unrelated to metaphysical Truth.
If believing a false answer can give you the same benefits as believing a true answer, and if there is no true answer available, then isn't the fool who believes the false answer the winner over the wise who believe nothing?
That might be true if (1) you thought the only purpose of belief were to "give you benefits" and (2) you assumed that those who believe nothing or have no interest in metaphysical Truth derive no benefits from their positions. I'm sure an atheist could describe all sorts of benefits he believes he derives from not being saddled with a wrathful God watching his every move. He's liberated to indulge in anything and everything that strikes his fancy - how much more "beneficial" could any belief system be than
that?
Of course that leads to another issue: what is truth? Maybe a religion is literally false but in spite of that a person who believes this religion gets most of the benefits promised? Is that religion false or true?
The ultimate metaphysical questions do have answers that are ontologically True. We cannot know those answers this side of the grave, but we can diligently attempt to get as close to them as we can. The answers we derive, tentative as they may be, will inform and guide every aspect of our earthly lives. The naturalistic/materialistic/atheistic paradigm
may be ontologically True, fundamentalist Christianity likewise
may be ontologically True - but I think it makes a vast difference whether we adopt one or the other because a diligent quest has led us to conclude that its the closest approximation of Truth or because we merely prefer the perceived "benefits."
What "benefits" one derives from one's belief system is almost entirely subjective. A false religion is not, in fact, true regardless of what benefits its adherents think they derive or even do derive. (This is one of the selling points of Christianity. It's so completely contrary to what most people would prefer to believe, so counterintuitive, that it's hard to believe anyone would have invented it.)
There is only one metaphysical Truth. My interest is in getting as close to it as I can, regardless of where the quest leads me. Supposed "benefits" are not going to influence my thinking.
