In mod.Eng. the comparatives in -er are almost restricted to adjs. of one or two syllables; longer adjs., and also disyllables containing any suffix other than -y or -ly, having the periphrastic comparison by means of the adv. more. Earlier writers, however, have beautifuller, eminenter, slavisher, etc.; a few modern writers, e.g. Carlyle, affect the same method. The periphrastic form is admissible (esp. in predicative use) for all adjs., even monosyllables, which are not extremely common colloquially.
So, 'more' and 'the most'forms are correct, stupider, the stupidest are sometimes used but they are not correct....
