Task C: Avoiding common errors in scientific writing

Summary

Ask any lecturer - there is nothing more off-putting than to read an assignment that is full of minor writing errors. Correct writing is not only important for success in your studies, but also in your professional life. Learning to write in the correct scientific style is a long-term project, so use your studies as an opportunity to identify and correct any problems you may experience.

Challenging your computer spell checker

The spell checker is an excellent tool to assist your writing; however, you need to understand its limitations. Hitting the wrong key may create a typo (not the word you intended, e.g. pedal instead of petal). If the typo is spelt correctly, spell check will not let you know. Spell check won't be able to help you with homophones (e.g. who's/whose, principle/principal) and other commonly confused words (affect/effect, parameter/perimeter). All your marker will see will be a paper full of careless/unusual errors. You will need to proofreadyour work carefully in the final stages of your writing.

Activity

Each of the sentences below contains an error that was missed by the spell checker. Read the following sentences and click on the incorrect word.

Exercise 1

The reason why rabbits are considered to be a serious pest in Australia is their large population density and their feeding and burrowing habits.

Choosing your words to reflect the nature of scientific thinking

Science is a way of thinking and knowing about the world and writing in science needs to reflect this. One of the characteristics of scientific knowledge is that although scientific theories can be strongly supported, they cannot be proved (though they can be disproved). In addition, be careful not to imply that natural systems or organisms follow some design or purpose, or that non-human things experience human emotions. This section gives you some examples of dealing with these issues.

Scientific proof

Many currently accepted philosophies of science argue that scientific phenomena cannot be proven, in the sense that they cannot be considered absolutely, incontrovertibly true. Therefore, try to avoid using the words prove or proof. Instead, use expressions such as indicate, strongly support, or strongly suggested by the evidence.

For example:

Bean seedlings grown in the dark were yellow, etiolated and eventually died, proving that light is necessary for plant growth.

Bean seedlings grown in the dark were yellow, etiolated and eventually died, indicating that light is necessary for plant growth.

The second sentence is preferable, as it is a more scientifically defensible description of the reason why the bean seedlings died.

Activity

Rewrite the following sentences, in the scratchpad provided, to avoid using proven or proving.

It has been proven that global warming is a consequence of greenhouse gas emissions.

The weight of evidence clearly shows that global warming is a consequence of greenhouse gas emissions.


The indicator turned yellow, proving that the solution was acidic.

The indicator turned yellow, showing that the solution was acidic.

Teleology

A common form of teleology is writing as if an organism or natural system has foresight, or is aiming towards a particular goal. Teleological expressions should be avoided in formal science writing.

For example:

Lianas grow up the trunks of rainforest trees so they can reach more light at the canopy.

Lianas grow up the trunks of rainforest trees, and this places their leaves in the higher light levels at the canopy.

The first sentence is an example of a teleological expression. Although the result of lianas growing up trees is that their leaves are in the sun, we cannot assume that this was the goal of the growth.

Activity

Rewrite the following sentences, in the scratchpad provided, to avoid the teleological expressions.

Arthropods have evolved a hard exoskeleton in order to protect their bodies.

Arthropods have evolved a hard exoskeleton that protects their bodies.


Primates have developed a number of characteristics to help them live in trees.

Primates have developed a number of characteristics that help them live in trees.

Anthropomorphism

Anthropomorphism is writing as if a non-human thing possesses human emotions or attributes. Anthropomorphism is quite common in informal, non-scientific language, but should be avoided in formal science writing.

For example:

Hermit crabs like to live in snail shells, although they will also live in other shells.

Hermit crabs inhabit snail shells more than other shell types.

The first sentence is an example of an anthropomorphic expression. It is unscientific to presume that hermit crabs have likings.

Activity

Rewrite the following sentences, in the scratchpad provided, to avoid the anthropomorphic expressions.

Insertion of the cannula did not upset the sheep.

Insertion of the cannula caused no signs of pain in the sheep.


The weeds preferred the sites with more fertile soils.

The weeds were more abundant in the sites with more fertile soils.

Try to follow scientific conventions relating to the nature of scientific proof, and avoid teleology and anthropomorphism in your scientific writing.
