Interest rates in Australia have just been reduced by 0.5% in the hope that this will stimulate the economy. Will it work? Uncertain. But will politicians say it will work in the coming federal budget? Almost undoubtedly.

Perhaps displays of optimism are not such a bad thing, even if they are unwarranted.

In a study that just came out, we (myself, David Johnston at Monash and Gigi Foster at UNSW) found that optimistic expectations are key to making  people happy with their lot in life. People are much less affected by regret than previously thought, nor do they tell themselves things will be bad in the future so that the present will be a pleasant surprise: people systematically over-estimate how rosy the future should be and this is crucial for their well-being.

Our study, of which the working paper version is here and the on-line article is here (for those with access) has the following highlights:

  1. In a sample of over 10,000 Australians followed for 9 years (the HILDA), it turns out that people’s expected future health has about 1/6th the effect on current happiness as their actual current health, with any difference between the health that was expected and that eventuated having very little effect.
  2. Future imagined health was more important to Australians over 35 and to women than to men and those under 35, for whom future imagined health was not important for happiness.
  3. As a result, we concur with the medical literature that has long argued that hope is important in itself for health, as witnessed by the strong placebo effect. In the medical literature hope has now become the default standard for new medicines in that new medicines have to be better than placebos if they are deemed to be of real use. Our advise is also to err on the side of optimism whenever possible.

Now, to classically trained economists, the fact that hope itself is a consumption good quite apart from realised consumption may be surprising, but in the reality of economic policy the big lesson from this kind of finding has been incorporated long ago: always pretend the economy will keep going strong or will soon improve unless there are really strong indications to the contrary. Hang on to see many an overly optimistic statement in the Federal budget next week …. and rightly so.

    So, don’t tell people the truth about our worldwide economic problems because people might worry too much?  Not telling the truth leads to one never identifying and actually fixing the core problems and to mal-investments that only exacerbate the problems.

    Totally agree with this, but I am not sure how to debate this, as there are way to many ends to the discussion that I am just not able to see. Keeping the morale up is good, and keeping your soldiers in the dark is a technique advocated by the strategist Sun Tzu. What I do know is that media has a lot of negative influence on the world. We have become so desensitized to the stories of wars and diseases that we are subconsciously thirsting for good news. Just take a look at videos on youtube promoting happiness and community and note the positive comments that the videos are getting. I think that it is important to not lie to the public, but it is also important to provide positive reinforcement and to foster a positive attitude within the people. This is a very difficult debate, because it reaches into the very freedoms we have as people. Perhaps I will write something on my blog on http://www.errant.ca.

    Winston,
     
    yes there is a loss in being optimistic to do with not being prepared to see bad things coming and do something about it. Its a balancing act.
     
    David,
    yes, the role of some media seems to be to talk badly about things. Not all though: many a magazine is an optimism-fest. Every time I read a science magazine I am full of hope we will solve all problems soon.
    I agree though that in many ways the sniping you see a lot in the media, particularly by anonymous bloggers, is the exception rather than the rule: in daily interaction where people see each other, optimism usually rules. Except in France of course.
