In the Bible is there any mention of how smart or stupid large groups of people are?
- Anybody can ask a question
- Anybody can answer
- The best answers are voted up and rise to the top
I'm not sure I would really use this to make a case for 'crowdsourcing' though.
No, not really. Half the time 'crowds' are mentioned the word is basically synonymous with 'mob' and the other half it's just a big group of people.
There is advice about seeking counsel from wise friends. The company you keep is important, and there are lots of stories (both good and bad) to show that. Most importantly, the Bible says that true wisdom always starts with knowing and rightly fearing the Lord, and that any understanding comes after that.
As Christians our source of wisdom should always be first and foremost God's word, and having a few sound counselors to help us in understanding it rightly. If we do not know and fear God it cannot be said that we are wise.
