# Is personality set in stone?

Myths, facts and data on personality over time

An accurate, validated personality profile is worth its weight in gold in recruitment and development. But how long does that picture hold true? Can an employee genuinely shift their deeper traits, or are we recruiting for fixed patterns?

People change throughout their lives, but they do so neither at random nor overnight. Understanding how our personality matures, shifts and responds to external circumstances is not just classic psychology; it is a decisive strategic business advantage.

Is personality set in stone? Myths, facts and data on personality over time

## What does the whitepaper explore?

Drawing on extensive data from the OPTO personality test and the latest research in the field, this whitepaper dives into the true nature of personality.

We examine which traits remain stable, where the greatest potential for development lies across generations, and how you turn that knowledge into concrete results in your organisation.

Here's what you'll take away from this whitepaper:

- **Insight into measurement:** How the Big Five Model creates a data-driven, objective language for human behaviour.
- **The formula for change:** The five primary catalysts that genuinely shift behaviour and drive personality development.
- **Generational differences in practice:** A statistical review of how personality develops from the young new hire to the experienced senior.
- **Strategic retention:** Why senior employees are not "fully developed", and how you keep motivating your organisation's most experienced profiles.
