In scientific writing, it is generally preferred to avoid contractions. Contractions are informal and can make scientific writing appear less professional. However, there may be certain situations where using contractions is appropriate. Here are some guidelines for when you can use contractions in scientific writing.
1. Informal writing
If you are writing for a less formal audience, such as a blog post or a popular science magazine, you may use contractions. These types of publications often aim to be more accessible to a general audience. In such cases, using contractions can make your writing more conversational and engaging.
2. Direct quotes
If you are quoting someone directly in your writing and they used a contraction, you should keep the contraction in the quote. Direct quotes should accurately capture what someone said or wrote, so it would be incorrect to change a contraction to its expanded form.
3. Emphasizing informality
In certain instances, contractions can be used to emphasize informality. For example, if you are discussing a study with a colleague and want to convey a more casual tone in your conversation, you might use a contraction.
Overall, it is best to avoid contractions in scientific writing. However, there are some exceptions where they may be appropriate. When in doubt, consult your style guide or supervisor for guidance on the use of contractions in scientific writing.
