Firstly a simple thanks for your continued efforts to share tools in an effort to help others. This particular effort however, in my personal opinion, is not your best effort and really quite alarming. If we take for granted that most good organizations employ selection methods that ensure parity for applicants i.e each candidate navigates the same process and procedures allowing the recruiters to compare them against each other and of course in the final stages be subject to more subjective opinion regarding relationship match with line managers and other colleagues etc, I think your presented methodology has just put the industry back 50 years.
Having spent many years as a police officer and being drilled to not submit to my 'gut instinct' or 'stereotyping' and studied such academically, the content of the powerpoint is the equivalent to whichcraft, old wives tales and potentially the basis of a law suit should candidates discover that their failure in the selection process was attributed to one of the characteristics cited. Consider scenario:
Final three candidates, having successfully completed a 2 day selection process with equal results are presented to the panel of selectors. Each again score equally to the questions presented but you have only one position available. With this powerpoint in your toolbag you suggest that the first candidates eyes were blue, the second had a broad nose and the third a head that doesn't fit the inverted oval template. You make your decision on the only thing that you think sets them apart and you provide honest feedback at the conclusion of the selection process. Think about it!
Although our gut instincts and stereotypes cannot be ignored, for they are what nature provided us for self-protection, we should be happy that we have come out of the cave and have developed systems of selection that wouldn't dare include any of the characteristics shown in the ppt. I wouldn't have promoted you for your effort but found a suitable course of study that would harness your interst and benefit the company.
Please consign your atavistic powerpoint to the museum it came from and continue your valuable contributions in the modern light of day.
