Just came across an actual figure for the existential risk posed by experiments at the Large
Hadron Collider:<br><br><span><a href="http://www.nzherald.co.nz/topic/story.cfm?c_id=325&objectid=10400645" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://www.nzherald.co.nz/topic/story.cfm?c_id=325&objectid=10400645

<br>Dr Cox dismissed worries that by adventuring into
the unknown and creating tiny black holes, the machine could even
destroy the planet.<div style="line-height: 10px;"> </div>"The probability is at the level of 10 to the minus 40," he said.<div style="line-height: 10px;"> </div></span><br>...<br><br>With that number, against the probability of other existential risks (eg: Gamma-Ut Ray Mi Burst), the risk is negligible against the noise.
<br><br>Question is: are these the real chances, or are they skewed by cognitive biases?<br><br> <br>
