Career changers may be screened through historical titles and tenure rather than current, job-relevant evidence, making transitions costly and path-dependent.

Prior titles, employer names, gaps, and occupational history influence screening because they are easy to read, while emerging capability is harder to verify. Technology can also depreciate once-valuable skills. The problem is path dependence—not proof that employers irrationally trap all career changers.

What the evidence does not prove

Supported by cited sources

Prior titles contain real information, and licensing, safety, geography, caregiving, wages, and preferences can constrain transitions regardless of proof. A project artifact cannot bypass regulated competence.

Why different stakeholders can care

Proposed

Workers gain resilience; employers gain overlooked talent; regions adapt to industrial change; and reskilling produces current evidence rather than only another completion claim.

Question to investigate

Open question

What The Solar Guild must test

Research question

Can a career changer complete an Objective in a new domain and earn a credible next step without overstating the narrow capability demonstrated?
