It's entirely because of human nature - you want people to get invested in it, which having them bid any amount does.

It's the same reason an auction can go above the price/value of the thing, because you get invested in your $x bid, so $x+5 doesn't seem like paying $x+5, but instead "only $5 more to preserve your win" type of thing.

See penny auction scams - https://utahjustice.com/penny-auction-scams - for an extreme example.
