It's a flaw in the rules that allows very-low-Intelligence characters to know three languages when in reality they would barely know one.
If you're not willing to roleplay a dumb or clumsy or weak character then don't put the low roll there.
Also, keep in mind we're talking about the extreme-outlier ends of the bell curve here. Further, 3-4-5e with their linear bonus structure suggest a far greater practical difference between a 8 and a 14 in any stat than do the IMO much more reasonable 1-2e setups where the bonus is j-curved at each end to better match the bell curve and has a big +0 region in the middle.
You do realize there's more than one way to play this game we all love, right? (well, maybe not all... but most of us)
