" let people talk to each other then they're influenced by other people's information and conform to what others are saying, rather than what they honestly think the right answer is."

Very much so :)

Which then leads to blaming those who came up with a certain idea, in case it turns out to be detrimental. It is always easier to point with the finger at others and leave them holding the baby. But we very well see that WE were the ones who let it come that far by deciding to evade own independent internal decision-making and stick to it. OUR choice.
The ego's evasion from responsibility brings short-term comfort at best (relief after successful escape), yet long-term discomfort.
Own decision-making brings short-term discomfort at worst ( external re-action trusting our faith in our own decision, or: our ego's doubt reflected externally), yet long-term comfort.

All points you list are very valid and true, noting to add ;)
