The major reason behind this slump was the recent economic recession, which had significant impact on the global banking sector. This is the standard measure of mutual fund out-performance. Michael Shermer in Scientific American  and Larry Smith of the University of Waterloo  have described how advice about commercial success distorts perceptions of it by ignoring all of the businesses and college dropouts that failed. These problems become especially significant when. Our newsletter keeps you up to date with all new papers in your subjects.

It often causes the results of studies to skew higher because only companies which were successful enough to survive until the end of the period are included. For example, a mutual fund company's selection of funds today will include only those that are successful now. Many losing funds are closed and merged into other funds to hide poor performance.
In , Elton, Gruber, and Blake showed that survivorship bias is larger in the small-fund sector than in large mutual funds presumably because small funds have a high probability of folding.
This is the standard measure of mutual fund out-performance. Additionally, in quantitative backtesting of market performance or other characteristics, survivorship bias is the use of a current index membership set rather than using the actual constituent changes over time. To use the current members only and create a historical equity line of the total return of the companies that met the criteria would be adding survivorship bias to the results.
Using the actual membership of the index and applying entry and exit dates to gain the appropriate return during inclusion in the index would allow for a bias-free output. Michael Shermer in Scientific American  and Larry Smith of the University of Waterloo  have described how advice about commercial success distorts perceptions of it by ignoring all of the businesses and college dropouts that failed. When something becomes a non-survivor, it is either completely eliminated, or whatever voice it has is muted to zero".
In his book The Black Swan , financial writer Nassim Taleb called the data obscured by survivorship bias "silent evidence. Diogenes was asked concerning paintings of those who had escaped shipwreck: Susan Mumm has described how survival bias leads historians to study organisations that are still in existence more than those which have closed. This means large, successful organisations such as the Women's Institute, which were well organised and still have accessible archives for historians to work from, are studied more than smaller charitable organisations, even though these may have done a great deal of work.
A commonly held opinion in many populations is that machinery, equipment, and goods manufactured in previous generations often is better built and lasts longer than similar contemporary items.
This perception is reflected in the common expression "They don't make 'em [them] like they used to". Again, because of the selective pressures of time and use, it is inevitable that only those items which were built to last will have survived into the present day. Therefore, most of the old machinery still seen functioning well in the present day must necessarily have been built to a standard of quality necessary to survive. All of the machinery, equipment, and goods that have failed over the intervening years are no longer visible to the general population as they have been junked, scrapped, recycled, or otherwise disposed of.
Though survivorship bias may explain a significant portion of the common perception that older manufacturing processes were more rigorous, there are other processes that may explain that perception, such as planned obsolescence and overengineering. It is difficult to directly compare and determine whether manufacturing has become overall better or worse. Manufactured goods are constantly changing, the same items are rarely built for more than a single generation, and even the raw materials change from one era to the next.
Capabilities and processes in materials science, technology, manufacturing, and testing have all advanced immensely since the 20th century, undoubtedly raising the potential for similar increases in durability, but pressures on production costs and time have also increased, resulting in manufacturing shortcuts that often result in less durable products.
Again, bias arises from the fact that historical goods of poor quality are no longer visible, and only the best produced items of the past survive to today.
Just as new buildings are being built every day and older structures are constantly torn down, the story of most civil and urban architecture involves a process of constant renewal, renovation, and revolution. Only the most subjectively, but popularly determined beautiful, most useful, and most structurally sound buildings survive from one generation to the next. This creates another selection effect where the ugliest and weakest buildings of history have long been eradicated from existence and thus the public view, and so it leaves the visible impression, seemingly correct but factually flawed, that all buildings in the past were both more beautiful and better built.
Whether it be movie stars, or athletes, or musicians, or CEOs of multibillion-dollar corporations who dropped out of school, popular media often tells the story of the determined individual who pursues their dreams and beats the odds. There is much less focus on the many people that may be similarly skilled and determined but fail to ever find success because of factors beyond their control or other seemingly random events. The overwhelming majority of failures are not visible to the public eye, and only those who survive the selective pressures of their competitive environment are seen regularly.
During World War II, the statistician Abraham Wald took survivorship bias into his calculations when considering how to minimize bomber losses to enemy fire. Wald proposed that the Navy reinforce areas where the returning aircraft were unscathed : His work is considered seminal in the then-fledgling discipline of operational research.
In a study performed in it was reported that cats who fall from less than six stories, and are still alive, have greater injuries than cats who fall from higher than six stories. In , The Straight Dope newspaper column proposed that another possible explanation for this phenomenon  would be survivorship bias.
