Informing participants that all participation is optional is the best way to ensure that their involvement is voluntary. When researchers clearly communicate that participants can choose whether or not to engage in the study without any repercussions or penalties for declining, it fosters an environment of autonomy and respect. This transparency helps to empower participants to make informed decisions about their involvement, aligning with ethical principles of informed consent and voluntary participation.

Emphasizing potential personal benefits can create an expectation or pressure for participants to take part, potentially undermining their perception of choice. While financial incentives might encourage participation, they can also introduce coercion or undue influence, especially if participants feel they need the financial support. Requiring participants to sign a contract may imply a mandatory obligation rather than a voluntary choice, which contradicts the principle of voluntary participation. By signaling that participation is truly optional, researchers uphold ethical standards while ensuring that participants feel comfortable making their own decisions.
