You commit the same reasoning flaw by dismissing the claim simply because of who made it rather than deal with the merits or demerits of the claim made. It's called ad hominem, meaning to the man. It is irrelevant because it sidestep the need to deal with the claims and simply attacks the person making the claim. It is just as invalid as dismissing or discrediting the arguments raised against JB properties simply because they were raised by people critical of JB properties.
What are you talking about? Haha... We are not having Philosophy101 class here!
Where's my flaw?
It's more like you are flawed in your perspective because it is one sided.
My statement might have been flawed if there is no strong evidence that there is a high oversupply of Iskandar properties. You can easily read the reports, facts and data online. Mind you, these are not from untested sources. They are from property analysts, the banks (local and even Malaysians), the Singapore government and academics. You must be either blind or deeply delusional to avoid accepting them.
All these data did not appear back in 2013. If so, the number of buyers of Iskandar properties might be much less than now.
So, let me give you an analogy. Suppose 10 people around you tell you not to visit a food stall because the food there tastes lousy. But you insist on going there. Then you ask a man standing near the stall: "Eh, can I know if the food here is delicious?" The guy replies: "Yes, it's good!" Now I come to you and say: "Do you know he is the owner of the stall? Of course he will say it's good."
Are you stupid enough to say my reasoning is flawed and go ahead to buy the food?
Sure, we can go on and on with the philosophical argument. Oh, maybe your taste bud is different. Maybe you will like the food, unlike the rest. But such arguments are trivial.
I think I've made my point. As xebay11 put it, the above is called "vested interest". You don't read an optimistic article and go YEAH! immediately. Think harder where the source is coming from.
