Expert writing Tips

Best practice

Use "how could you" to express surprise, disbelief, or reproach, but be mindful of the tone. Overuse can come across as overly accusatory. Consider softening the phrase with additional context to mitigate potential harshness.

Common error

While "how could you" is acceptable in many situations, it may be too informal or emotionally charged for professional settings. In formal communication, consider more neutral alternatives such as "can you explain the reasoning behind" or "what factors led to this decision".
