This verse suggests that even a fool, when silent, is considered wise, and thus promotes prudence over open expression, which could contradict valuing someone for their wisdom in expression as in Proverbs 12:8.
Proverbs 17:28: Even a fool, when he holdeth his peace, is counted wise: [and] he that shutteth his lips [is esteemed] a man of understanding.

Here, wisdom is said to be better than strength, yet the poor man's wisdom is despised and his words are not heard, contradicting Proverbs 12:8, which seems to imply that wisdom should bring praise.
Ecclesiastes 9:16: Then said I, Wisdom [is] better than strength: nevertheless the poor man's wisdom [is] despised, and his words are not heard.

Contradiction with Ecclesiastes 7:25
Solomon's quest to find wisdom resulted in finding foolishness, thus suggesting that wisdom may not be as praiseworthy or attainable as Proverbs 12:8 implies.

Matthew 23:12: And whosoever shall exalt himself shall be abased; and he that shall humble himself shall be exalted.
