Survivorship bias refers to an issue in statistical analysis where a significant portion of potential cases aren't available to be counted, and therefore aren't included in the statistics, which creates a data set which is biased toward the cases that are counted. In this case, the people who are invited to and willing to give such speeches are overwhelmingly people who achieved success. People who are unsuccessful tend not to be highlighted or publicized, even if they followed the same path and made the same efforts as those who became successful.&amp;#160; This is especially important because achieving success usually involves taking risks. If those risks pay off and result in success, a person will often be lauded as an example of achievement, but if the risk doesn't pay off, they'll often be ignored. This can result in a skewed view of how certain risks are to result in positive outcomes. &amp;#160;&lt;/div&gt;&lt;/td&gt;&lt;td class='diff-marker'&gt;&amp;#160;&lt;/td&gt;&lt;td style=&quot;background-color: #f9f9f9; color: #333333; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #e6e6e6; vertical-align: top; white-space: pre-wrap;&quot;&gt;&lt;div&gt;As the title and caption both suggest, a major problem with these speeches is {{w|survivorship bias}}.

Survivorship bias refers to an issue in statistical analysis where a significant portion of potential cases aren't available to be counted, and therefore aren't included in the statistics, which creates a data set which is biased toward the cases that are counted. In this case, the people who are invited to and willing to give such speeches are overwhelmingly people who achieved success. People who are unsuccessful tend not to be highlighted or publicized, even if they followed the same path and made the same efforts as those who became successful.&amp;#160; This is especially important because achieving success usually involves taking risks. If those risks pay off and result in success, a person will often be lauded as an example of achievement, but if the risk doesn't pay off, they'll often be ignored. This can result in a skewed view of how certain risks are to result in positive outcomes. &amp;#160;&lt;/div&gt;&lt;/td&gt;&lt;td class='diff-marker'&gt;&amp;#160;&lt;/td&gt;&lt;td style=&quot;background-color: #f9f9f9; color: #333333; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #e6e6e6; vertical-align: top; white-space: pre-wrap;&quot;&gt;&lt;div&gt;As the title and caption both suggest, a major problem with these speeches is {{w|survivorship bias}}.
