You don't need to know much about psychology to understand...

You don't need to know much about psychology to understand confirmation bias and the tendency to only listen to people that believe your own point of view... given the majority of posters on this board up until about a week ago were long termers everyone had the same point of view, which is why they are all long termers in the first place.

Long termers don't refresh forums every 5mins and try and warn others that the price is overheated etc., they are generally working their day job or on the golf course or generally following Warren Buffets advice to only buy a share that you'd be comfortable buying if you couldn't sell it for ten years.

You didn't need to look far to find independent opinions outside HotCopper advising that the price was overheated:

"Hawsons is an iron ore developer and producer. It’s focusing on developing its iron project near Broken Hill. The share price has risen from 17 cents on March 1, 2022 to trade at 58 cents on April 28. At current levels, I believe the stock has moved too hard too fast, so investors may want to consider locking in some gains to manage risk."

Ultimately people on a forum can talk up a stock as much as they like you need the discipline to filter out the bias (positive or negative), focus on your own trading strategy and make (and own) your own decisions.
