Australia needs more people who think like scientists. Here’s what that means

Australia needs more individuals who think like scientists, as their curiosity and ability to reason are essential in navigating an increasingly complex world. One example is Hannah, who was captivated by the way a prism divides sunlight into various colors during her childhood. This fascination led her to study the interaction of light with liquids at university, where she now works in the food industry using light to analyze oat milk when combined with hot coffee.

This demonstrates how early interest in science can translate into valuable skills applicable to modern industries like food production.

However, Australia faces a shortage of individuals studying science, which limits our potential to utilize scientific tools for understanding and improving our world. Science literacy encompasses more than just knowledge; it involves the capacity to reason, evaluate evidence, and make informed decisions amidst a world rife with misinformation on topics such as climate change, renewable energy, and artificial intelligence.

Employers highly value the skills cultivated by science graduates, including adaptability, problem-solving, communication, and digital literacy.

The Australian government has shifted its focus towards "job-ready" education and vocational training, which may discourage students from pursuing science degrees. This approach, combined with parental attitudes that emphasize choosing subjects that lead to secure careers, has contributed to students gravitating towards fields like nursing, engineering, and law. Consequently, there's a growing disconnect between scientific training and employment opportunities.

Although some science-related careers, such as agricultural science, offer clear pathways into industry, many young Australians remain unaware of the diverse career options available with science degrees. A decline in enrolments in subjects like chemistry and physics, which form the foundation of fields like materials science, further exacerbates this issue. Despite a stable number of science students at Australian universities, their proportion among all university enrollments has been decreasing.

The demand for material scientists and other professionals in emerging technologies like electronics, medicine, energy production, and space science is on the rise. However, the slow response of students to changing job market demands and the long lead time needed to build a science workforce present challenges. A recent government report indicates that the professional, scientific, and technical services industry is projected to grow faster than any other sector, except healthcare, in the next five years. To address this, it's crucial to bolster the science pipeline promptly.

Science graduates often work in diverse fields beyond traditional lab settings. The misconception that "all scientists wear white coats" is outdated, as the majority of science graduates find employment in business, government, policy, education, and technology. Notably, a significant number of Fortune 100 chief executives hold Bachelor of Science degrees, highlighting the broad applicability of scientific skills.

The high value of science graduates in various industries is evident, with advanced physical and mathematical sciences contributing approximately 11% of Australia's GDP.

To revitalize Australia's science pipeline, efforts must begin at an early age. Primary school education should incorporate engaging and inspiring science activities to foster curiosity and interest. High school students should be encouraged to continue studying science without undue pressure to prioritize high ATAR scores or university admissions, as this can deter them from engaging with complex scientific subjects.

Universities must improve communication of the wide array of career opportunities available to science graduates and demonstrate the practical value of science skills in different workplaces.

Governments should also play a role by encouraging industry investment in research and development, thereby increasing the visibility and demand for science-related careers. Ultimately, exposing students to science through activities such as National Science Week, visits to science centers, and discussions with family members about the relevance of science can help prepare the next generation for an uncertain future.
