A recruitment panel can compare degrees, certificates and professional memberships in minutes. It is far harder to assess the quality that often determines whether a difficult decision succeeds: judgement. The debate over experience versus academic expertise is therefore not a contest between clever people and practical people. It concerns two different forms of knowledge, and the costly mistake of treating the one that is easiest to record as the one that matters most.
Britain is at risk of making precisely that mistake as experienced engineers, exporters, technicians, civil servants and managers retire. Their replacement may arrive well qualified, energetic and entirely capable of learning. Yet a qualification cannot transfer the accumulated understanding of what happened last time, why a foreign customer hesitated, where a specification is likely to fail, or which apparently tidy policy will cause difficulty on the ground.
