13. CriticalThinking is a domain-general thinking
skill.
The ability to think clearly and rationally is
important whatever we choose to do. If you
work in education, research, finance,
management or the legal profession,
then critical thinking is obviously important.
But critical thinking skills are not restricted to a
particular subject area. Being able to think well
and solve problems systematically is an asset for
any career.

14. Critical Thinking enhances language and
presentation skills.
Thinking clearly and systematically can
improve the way we express our ideas. In
learning how to analyse the logical structure
of texts, critical thinking also improves
comprehension abilities.

15. CriticalThinking promotes creativity.
To come up with a creative solution to a
problem involves not just having new ideas. It
must also be the case that the new ideas
being generated are useful and relevant to
the task at hand. Critical thinking plays a
crucial role in evaluating new ideas, selecting
the best ones and modifying them if
necessary

16. Critical Thinking is crucial for self-
reflection.
In order to live a meaningful life and to
structure our lives accordingly, we need to
justify and reflect on our values and
decisions. Critical thinking provides the tools
for this process of self-evaluation.
