I recently came across a post on the Victor Niederhoffer Blog about the concept of Confirmatory Bias. I shall reprint the standard quote from Sir Francis Bacon that is used in much of the literature on this subject:
"The human understanding when it has once adopted an opinion (either as being the received opinion or as being agreeable to itself) draws all things else to support and agree with it. And though there be a greater number and weight of instances to be found on the other side, yet these it either neglects and despises, or else by some distinction sets aside and rejects; in order that by this great and pernicious predetermination the authority of its former conclusions may remain inviolate..."
After searching further, I came across a paper published in the Review of General Psychology in 1998 authored by Raymond S. Nickerson of Tufts University. I believe that the concepts he discusses have applicability to current beliefs by bullish energy investors in the oil market.
He presents a modern definition of the concept of Confirmatory Bias;
"...the seeking or interpreting of evidence in ways that are partial to existing beliefs, expectations, or a hypothesis in hand."
In his paper he reduces the concept to its component parts.
I have already discussed the first two parts last week, and parts three and four here.
Today I present my own concepts. They don't really come under the strict definition of Confirmatory Bias, but they are certainly biases that support the bubble, and after all, its my blog and if I want to write about them I will.
Glorification of results or the market must be right.
Oil and Energy has been in a multi year bull market and if there is one thing I have noticed in investing, it is the presumption that because the "market" says something, then the "market" must be right. This is a situation where the "psychological high" that accompanies good investment results is substituted by investors for thorough analytical thought.
Commodities are up 50% this year, well there must be something to it. "These guys must know what they are doing, I guess I'm just not smart enough to figure it out," an investor mumbles under his breath as he heads to his broker, bitter about missing out on the good times.
I can find quotes to apply to other bubbles as well. How about this one for the Housing Bubble. "My neighbor owns five houses and flipped three last year, why can't I do the same? Home prices never go down so what do I have to worry about."
The Cheerleader Effect or talking heads on TV as the second coming of Jesus
Investors are constantly bombarded with information in support of the bull from talking heads on Television, either from professional investors, or from sell side analysts, the great facilitators of the bull market whose job it is to hold our hands while we continue our journey through commodity investing. All of these people have vested financial interests in the bull, and although this is disclosed, usually at the conclusion of the appearance, I don't think that it is generally understood.
This positive reinforcement has a huge unconscious effect on investors. I think that being on television somehow leads to this aura of omniscience that filters down to investors who watch them. Is it that hard to get on television? I don't know - they do need a constant flow of material to entertain us with.
What I do know is that sometimes it is hard to take what they say seriously when two weeks earlier, I saw the same guy during a conference, trying to fondle an 18 year old stripper who was bouncing around on his lap during the evening entertainment hour. Incidents like that tend to dissipate any aura around them in my eyes. These people are not Gods, they are not divine and they did not spring from the head of Zeus.
Investors will usually deny this effect, which can be subtitled "cult investing," but if you read between the lines you will see it is true. These analysts and pundits let you down before when it came to Internet stocks, and they let you down when it came to Real Estate. Are you going to believe them this time? Remember, Growth always disappoints in the end.
The misinterpretation of information usually by twisting it intentionally.
There is an entire cottage industry of analysts and talking heads whose job it is to manage and shape investors thoughts. If, God forbid, any bearish or contrary ideas begin to bubble up to the surface, it is their job to squash it in its womb, so nothing will impede the march of the Bull. As contradictory and bearish evidence begins to mount during the late part of a cycle, this becomes more and more difficult to do. This is the Wall Street equivalent of "spin control" in politics. Here is an example:
China and other Asian countries have partially removed subsidies on products refined from Oil, and sold to its citizens, many of whom have been shielded from the soaring cost of oil, and the resulting soaring cost of gasoline. So common sense would tell you that as the price of gasoline and other products go up, people should use less of it thus reducing demand. While this demand response tends to be closer to inelastic than elastic in the short term, there is an effect. Anyone who doubts this should look at highway miles driven in the United States the last three months.
Somehow this negative data point has been ridiculously twisted to instead mean that Asian countries will actually import more oil to refine into product because they can now lose less money than before, since they can charge more. So here's how it really works - if you sell 5 million gallons of gas and lose 50 cents a gallon you have lost $2.5 million. If you sell 10 million gallons and lose only 25 cents a gallon, well guess what, you've lost the same thing.
This reminds me of an old story that my father used to tell me. He worked in the garment or "schmata" business. After reviewing a new line of clothes, it was determined that to sell them at a competitive price, they would lose money on every piece they sold. The executive just leaned back in his chair, smiled and said, "don't worry, we'll make it up on volume."

Confirmatory Bias and Oil Investing - Part Two
I recently came across a post on the Victor Niederhoffer Blog about the concept of Confirmatory Bias. I shall reprint the standard quote from Sir Francis Bacon that is used in much of the literature on this subject:
"The human understanding when it has once adopted an opinion (either as being the received opinion or as being agreeable to itself) draws all things else to support and agree with it. And though there be a greater number and weight of instances to be found on the other side, yet these it either neglects and despises, or else by some distinction sets aside and rejects; in order that by this great and pernicious predetermination the authority of its former conclusions may remain inviolate..."
After searching further, I came across a paper published in the Review of General Psychology in 1998 authored by Raymond S. Nickerson of Tufts University. I believe that the concepts he discusses have applicability to current beliefs by bullish energy investors in the oil market.
He presents a modern definition of the concept of Confirmatory Bias:
"...the seeking or interpreting of evidence in ways that are partial to existing beliefs, expectations, or a hypothesis in hand."
In his paper he reduces the concept to its component parts. Yesterday, I discussed the first two parts, and today I present my discussion of Parts 3 and 4.
Number 3 - Overweighting positive confirmatory instances.
"Studies of social judgment provide evidence that people tend to overweight positive confirmatory evidence or underweight negative discomfirmatory evidence."
The International Agency Energy (IEA) last week revised its estimates for the supply and demand situation in oil. The part of the report that made the headline was its prediction that the oil market would remain "tight" for the next five years. What was ignored was the negative information that the IEA had cut demand growth from 2.2 to 1.6% per year on average for the next five years. Although this cut in demand came from the mature economies and not the emerging economies, it is the equivalent of 500 thousand barrel a day of demand being taken off the market. This equals all of the growth in China every year for the next five years.
Number 4 - Seeing what one is looking for.
"People sometimes see in data the patterns for which they are looking, regardless of whether the patterns are really there."
This is also very prevalent in oil markets. Every other week there is news about some labor strife in Nigeria, a major oil exporter. This usually results in a couple hundred thousand barrels a day being temporarily removed from the market, and a $4 dollar a barrel rise in price. Yet when Saudi Arabia increases production by 500 thousand barrels a day, the market doesn't care. Investors see a temporary supply disruption as permanent, and ignore a permanent increase.

Confirmatory Bias and Oil Investing - Part One
I recently came across a post on the Victor Niederhoffer Blog about the concept of Confirmatory Bias. I shall reprint the standard quote from Sir Francis Bacon that is used in much of the literature on this subject:
"The human understanding when it has once adopted an opinion (either as being the received opinion or as being agreeable to itself) draws all things else to support and agree with it. And though there be a greater number and weight of instances to be found on the other side, yet these it either neglects and despises, or else by some distinction sets aside and rejects; in order that by this great and pernicious predetermination the authority of its former conclusions may remain inviolate..."
After searching further, I came across a paper published in the Review of General Psychology in 1998 authored by Raymond S. Nickerson of Tufts University. I believe that the concepts he discusses have applicability to current beliefs by bullish energy investors about Oil.
Nickerson presents a modern definition of the concept of Confirmatory Bias;
"...the seeking or interpreting of evidence in ways that are partial to existing beliefs, expectations, or a hypothesis in hand."
In his paper he reduces the concept to its component parts. I will discuss four of them, and then present my own.
Number 1 - Restriction of attention to a favored hypothesis.
"If one entertains only a single possible explanation of some event or phenomenon, one precludes the possibility of interpreting data as supportive of any alternative explanation."
Oil bulls believe that the only thing that can explain high oil prices is the trite hypothesis currently circulating in the market - that strong demand from emerging economies and limited, or even peak supply, is responsible. All other evidence to the contrary is ignored. The possibility that "speculators" or "traders" or "momentum players" may be partly responsible for a premium is scorned.
This belief, of course, ignores 220 years of history in the American financial markets, where there have been many cases of market speculation and/or manipulation, from Erie Canal bonds to Railroad bonds to Internet stocks. The real question that one should ask is the inverse of this - is there any financial instrument and/or Commodity that hasn't been subject to speculation or manipulation or overvaluation?
Number 2 - Preferential treatment of evidence supporting existing beliefs.
"...the tendency to give greater weight to information that is supportive of existing beliefs or opinions than to information that runs counter to them. This does not necessarily mean completely ignoring the counter indicative information but means being less receptive to it..."
This is seen regularly in any statistical report issued regarding oil. If the Department of Energy (DOE) or the International Agency Energy (IEA) comes out with any report that challenges the bull - the report is "bad data." Any statistics that support the bull is trumpeted for the world to see, thus proving the investment case.
If economic activity in the U.S. and other OECD nations slows down, leading to less demand for oil, it doesn't matter, as long as demand in China continues to grow at its absolute number of 500 thousand barrels a day. The fact that a 2% contraction in oil demand by the OECD would be twice China's absolute growth is not given any weight by the market.
I will present Part 2 tomorrow.
