Echoing my series on the design talent crisis and other articles warning against the practice of cutting back on junior talent, Vaughn Tan offers yet another dimension: subjective decision-making skills are only honed through practice. But the opportunities given to junior staff for this type of decision-making are slim.

But to back up, here’s Tan explaining what subjective decision-making is:

These are decisions where there’s no one “correct” answer and the answers that work can’t be known in advance. Subjective decisionmaking requires critical thinking skills to make strongly reasoned arguments, identify appropriate evidence, understand the tradeoffs of different arguments, make decisions that may (or may not) be correct, and develop compelling narratives for those decisions.

While his article isn’t about AI nor is it about companies not hiring juniors, it is about companies not developing juniors and allowing them to practice this type of decision-making in low-stakes situations.

Critical thinking and judgment require practice. Practice needs to be frequent, and needs to begin at a low level with very few consequences that are important. This small-scale training in subjective decisionmaking and critical thinking is the best way to learn how to do it properly in more consequential situations.

If you wait until someone is senior to teach judgment, their first practice attempts have serious consequences. High-stakes decisionmaking pressure cannot be simulated realistically; learning how to deal with it requires actual practice with real consequences that progressively increases in scope and consequentiality.

And why is this all important? Not developing junior staff means there will be a bottleneck issue—only seniors can make these judgement calls—and one day, there will be a succession problem, i.e., who takes over when the seniors leave or retire.
