Another 14 ways our mind plays tricks on us as investors


We like to think we’re rational human beings.

However a few days ago I shared with you the concept that we are in fact prone to a group of cognitive biases that cause us to think and act irrationally, and this affects many of our investment decisions.

Even thinking we’re rational despite evidence of irrationality in others is known as blind spot bias.

I shared with you the concept of Confirmation Bias, which is the natural human tendency to seek information that confirms our pre-conceived conclusions.

In my view confirmation bias is a major reason for investment mistakes, so I recommended you always attempt to challenge the status quo and seek information that causes you to question your investment strategies.

I also showed how the Bandwagon Effect describes gaining comfort in something because many other people do, or believe, the same.

This is also called “herd mentality”, but we know “the herd” is usually wrong – most property investors never build a substantial portfolio.

So it pays to consider the concept of countercyclical investing.

I also discussed the concept of being biased towards overwhelming negativity or positivity – which often becomes apparent when couples are investing, and they realise they are in opposite camps.

Today in the second part of this 2 part series, I’ll examine some further ways the way our brains sneakily convince us to make decisions that aren’t always in our best interests.

1. The Ostrich effect

When an ostrich is scared, the bird supposedly buries its head in the sand to stay ignorant of the approaching threat.

The (lack of) logic is presumably: “If I can’t see it, it doesn’t exist.”

Silly, right?

Maybe it isn’t as ridiculous as it sounds, considering that humans do it, too.

While we simply don’t have the neck length to literally stick our heads in the sand, people often deliberately look away from their money problems.

Investor takeaway

Some investors avoid unpleasant information such as reading negative financial news or checking on the performance of their properties, while many Australians bury their heads in the sand about their future financial security and put off investing altogether.

On the other hand, successful investors read as much as they can, talk to others who have a different perspective, and surround themselves with positive supportive people who help them form an objective view of what’s going on.

2. Choice-supportive bias

Here you prefer the things you own (even if they have flaws) over the things you don’t because you made “rational” choices when you bought them.

For example, if a person buys a computer running Windows instead of one from Apple, he is likely to downplay the faults of Windows while amplifying those of Apple computers.

It’s just like when you’re convinced the investment you’ve just made is great because you spend so much time, research, and emotion in selecting it.

In fact, you rationalize your past choices to protect your sense of self.

Investor takeaway

Now you may not necessarily be wrong, but this is a bias you should be aware of in the future when reviewing the performance of your property portfolio.

3. Clustering illusion

This is the tendency to see patterns in random events.

This is particularly true of gamblers who desperately try to ‘beat the system’ by seeing patterns of events in cards or the roulette wheel.

Investor takeaway

We are ‘pattern machines’ and recognise people and things from their overall pattern rather than full detail.

While this is very useful, it does also mean we can see patterns where there are none.

This selective thinking can lead to wrong conclusions when faced with the multitude of mixed messages we receive about the property market.

4. Curse of knowledge

You suffer from the curse of knowledge when you know things that other people don’t and you’ve forgotten what it’s like to not have this knowledge.

For instance, in the TV show ‘The Big Bang Theory,’ it’s difficult for scientist Sheldon Cooper to understand his waitress neighbour Penny.

I see this in relation to property investment when I come across professionals who are successful in their own field and then believe they can translate that success into the arena of real estate.

Investor takeaway

Highly intelligent people often have difficulty asking for help or taking advice because they think they should be able to work things out for themselves.

So they try to tweak, improve and fine-tune someone else’s property investment strategy interpreting it with their own biases, and then wonder why it doesn’t work so well for them.

On the other hand, I’ve found that many successful investors are “dumb” – they just find a strategy that works well for their mentors and follow it implicitly.

If you’re the smartest person on your team you’re in trouble.

5. Overconfidence

This is the downfall of many investors.

In fact, one of the worst things that can happen to an investor is to get it right the first time they buy a property.

This often happens when you invest during a property boom because you tend to think you’re smarter than you are.

This occurred recently when beginning investors bought in mining towns and property values initially rose significantly.
