Something is statistically very fishy in there. If Sky (and Admiral)\u00a0can make such a sweeping assessment about such a complex subject based on such a tiny sample, it would appear highly likely that the actual analysis was flawed through not taking into account accident type, and so on.<\/p>\n<p>It&#8217;s also amusing that although it has taken 4 years to obtain the data and draw this conclusion, Professor Frank McKenna, a psychologist (so, not quite a real scientist) on the Parliamentary Advisory Council for Transport (so, not an unbiased employee, either),\u00a0makes this counter statement:<\/p>\n<blockquote>\n<p><span style=\"color: #000080;\">&#8220;The worst thing you can do with a young driver is increase their confidence without increasing their competence,&#8221; he said. <\/p>\n<p><span style=\"color: #000080;\">&#8220;If there&#8217;s no increase in competence you potentially run the risk of increasing the chance of accidents.&#8221; <\/p>\n<\/blockquote>\n<p>Let me emphasis this again: it took <strong>4 years<\/strong> to get enough data (and it&#8217;s debatable that it <em>is<\/em> enough) to conclude that\u00a0Pass Plus has a limited effect, yet a pseudo-scientist in the employ of the government\u00a0can come out with something like that <strong>in a few seconds<\/strong>&#8230; and get published as an authority! I suspect this is partly yet another LibCon attempt to smear the previous government.<\/p>\n<p>McKenna is expressing an opinion &#8211; opinion based on political leaning\/employment\u00a0&#8211; and not a fact.<\/p>\n<p>It doesn&#8217;t surprise me in the least that they can&#8217;t prove whether or not Pass Plus decreases accidents. Most of the time, drawing a neat conclusion even from a single accident is difficult, so adding a heap of these together is hardly going to give a definitive answer to the Meaning Of Life.<\/p>\n<p>Pass Plus is still a useful course. Any post-test training of this kind is &#8211; it <strong><em>HAS<\/em><\/strong> to be. However, it if there is no insurance benefit and comedians like McKenna appear to suggest incorrectly that it&#8217;s useless,\u00a0it&#8217;s hard to see what justification people will have for taking it.<\/p>\n<p>If McKenna can make statements of the obvious and use them out of context, the rest of us can make them and use them <strong><em>IN<\/em><\/strong> context&#8230;<\/p>\n<p>McKenna says it is dangerous to increase someone&#8217;s confidence without increasing their competence. That&#8217;s all he says, so you have to fill in the rest yourself (e.g. by implication, therefore, &#8220;Pass Plus is a dangerous course that is more likely to kill young drivers than to save them&#8221;).<\/p>\n<p>I say that <strong><em>ANY<\/em><\/strong> post-test training is beneficial and as long as it is delivered correctly it&#8217;s effects will be beneficial. <strong><em>ANY<\/em><\/strong> negative effects, such as driving dangerously, are entirely the responsibility and decision\u00a0of the driver. He or she can drive in a dangerous manner <em>before<\/em> taking a course, and most do. If a course doesn&#8217;t say &#8220;drive fast&#8221;, you cannot blame the course for things if people do.<\/p>\n<p>At the very least, not until you have years and years of statistical data instead of just a political axe to grind. Oh, and perhaps a proper scientific qualification if you&#8217;re going to dabble in complicated topics.<\/p>\n<p><strong> Courses provide additional tools and knowledge&#8230; they do not change attitudes. <\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>I saw this story on Sky News today.
