Or it may not.
Worse: If I use the agent, I don't know whether the agent gained me 6% of the price in the negotiations. If I don't use the agent, I don't know if I cost myself 6% of the price (or more!) in the negotiations.
Someone could do a study, looking at sale prices of "for sale by owner" versus sale prices of comparable sales through agents, for comparable periods. Even that study is fraught - for us to trust it, it would have to be by non-realtors, but also by people not involved in the "for sale by owner" world in some way. And yet the study would have to get the comparables right - not just right, but clearly right, so that the results of the study will be believed.
Without such a study, we're all kind of just believing what we believe.
The Freakonomics book went into this in detail.

If your house sales for $50K more, each agent gets $1500 more and the brokerage gets 20-40% of that. Let’s say 30%. That means the agent will get a little over $1000 extra.
They would much rather sell your house for $50K less and move on than convincing you to hold out for $50K more.
if we're all for transparent markets, these commissions interfere and it doesn't matter how close to reality they are as we can agree that they're largely not real, but synthetic amalgamations of something not related to the market.
Typically, agents (on both sides) are incentivized to doing whatever makes the sale happen with the least time, risk, and effort, because what they lose on commission if that involves a (not extraordinarily unreasonable) price cut they make up for in volume.
The argument I've seen made is that the buyer's agent's motivation to lower the price comes from wanting their client to actually make the purchase. That said, I'd think that this is only motivating them to get down to the highest price that the buyer will accept paying, rather than the actual lowest price that's theoretically possible.
I'm a better negotiator than any agent I've ever dealt with. Add in the white hot market the last decade and the only 'negotiation' happening was figuring out how much to overbid.
Not exclusive to realtors.
Many realtors works take a consulting fee too navigate things. Try.
Beyond that getting a lawyer to handle a sale doesn’t seem much different with or without a realtor. They have their own liability insurance.
Realtors def help navigate the market agent they are competent in it.
Neither of these things require an agent, and neither are worth $40K.
