There is only one final judge of who is right and who is wrong and that is Time.
The thing is I have been having this same argument on Hotcopper for many, many years and the exact same forecasts were being made then as they are now.
Time has proven all those people wrong but I haven't seen a single one come back on here to say "OK, I was wrong, I admit it".
Quite the reverse. One poster in particular is still on here 5 years after first forecasting diving property prices (and continuing every week of every month of every year since then), still making the same predictions and his argument now is "OK it didn't happen all those years I was predicting it but it has to happen now".
The stubborness is amazing to behold.
Was it Peter, Paul and May who sang "When will they ever learn? When will they evvveeerr learn?"
