I-O Psychologist
In the high-stakes and competitive world of employee selection, finding the perfect candidate can often feel like searching for a needle in a haystack. The process involves a multifaceted approach, encompassing not just the identification of the right skills and experience but also delving deep into uncovering the true personality traits that will ensure a seamless and perfect fit within your team.
With so much at stake and the potential impact on your organization's success, the tools and methodologies you use to assess personality are absolutely critical. It is essential to have a robust and comprehensive approach to evaluation that goes beyond the surface, ensuring that you can make informed and confident hiring decisions.
Enter the debate: Normative or Ipsative scaling?
Or, to put it another way, Likert scale versus forced-choice formats. At first glance, this might seem like an academic dilemma, but the stakes are real, and the implications are significant. Imagine a tool that can peel back the layers of social desirability bias and provide a clearer, more honest picture of your candidates.
Intrigued? Let’s dive into the world of personality assessments and discover which method holds the key to unlocking the true potential of your future hires.
Evaluating Candidates: Normative vs. Ipsative Approaches
In personality and behavioral assessments, normative and ipsative scaling forms represent two fundamental approaches to measuring responses.
Normative: Likert scale
Normative scaling, which is exemplified by the widely-used Likert scale, allows respondents to rate their agreement with various statements on a continuous scale. This method provides valuable comparative data across different individuals, offering a broad and insightful perspective on attitudes, preferences, and behaviors.
For instance, on a Likert scale, a candidate might rate their level of agreement with a statement such as "I enjoy teamwork" on a scale ranging from 1 to 5. This enables meaningful comparisons with other individuals who have taken the same assessment, thereby facilitating a comprehensive analysis of how different candidates perceive and align with specific traits and attributes. This type of scaling is particularly useful in creating a nuanced understanding of personality traits across a diverse group of respondents.
Ipsative: Forced-choice formats
Ipsative scaling, illustrated by forced-choice formats, requires respondents to make deliberate choices between a set of given options, thereby highlighting their relative preferences and strengths. For example, a forced-choice question might present a candidate with a decision to choose which of two statements is more reflective of their behavior, such as "I prefer to lead" versus "I prefer to follow."
This approach focuses on constructing detailed individual profiles and ensuring internal consistency within the responses rather than facilitating direct comparisons with others. By compelling candidates to make such specific choices, ipsative scaling aims to reveal the nuanced aspects of a person's personality and preferences. This method provides a clearer, more individualized picture of their inherent tendencies, which can be crucial for aligning their potential fit with specific roles or work environments.

Normative vs. Ipsative Approaches in Selection Assessments
Despite the valuable insights provided by ipsative scales, normative scaling tends to be more favorable in selection assessments. The comparative data generated by normative methods, such as the Likert scale, enables a more comprehensive and detailed analysis of candidates' qualities relative to one another. This ability to compare responses across a broad spectrum of individuals offers significant advantages in understanding how each candidate measures up in terms of specific attributes and behaviors.
This broader perspective is particularly valuable in selection contexts, where the primary goal is to identify the best-fit candidates based on a wide range of attributes and behaviors. By leveraging the comparative data from normative scaling, hiring managers can make more informed and balanced decisions. This comprehensive approach often proves more effective in achieving the desired outcomes of the hiring process, ensuring that the most suitable candidates are selected for the roles in question.
Forced-Choice Formats: Friend or Foe?
As mentioned above, forced-choice formats in employee selection present candidates with challenging decisions, requiring them to choose between equally positive traits. When it comes to personality assessments in employee selection, the forced-choice format has its unique set of advantages and challenges.
Benefits of Forced-Choice Formats
One of the key benefits is the reduction of response bias, particularly social desirability bias. Forced-choice questions make it harder for individuals to present themselves in an overly favorable light consistently. This can lead to more genuine insights into their true preferences and tendencies. For instance, when asked to choose between being "very organized" and "very creative," candidates reveal more about their priorities. Moreover, forced-choice formats enhance discrimination among candidates. By compelling respondents to make difficult choices, this approach helps differentiate those who naturally lean towards certain traits over others. This can be useful in distinguishing between candidates who might otherwise seem similar.
Drawbacks of Forced-Choice Formats
However, these advantages come with significant drawbacks. The complexity of scoring forced-choice assessments can be daunting, often necessitating advanced statistical techniques to ensure balanced and fair results. This complexity can make both the development and interpretation of these assessments more challenging. Furthermore, candidates may experience frustration with forced-choice questions, particularly when they feel none of the options accurately reflect their views. This frustration can potentially lead to disengagement or lower-quality data.
Another critical issue is the limited variation that forced-choice formats offer. By simplifying complex opinions into binary choices, these assessments might miss the subtle gradations in candidates' attitudes and behaviors. For example, a candidate who values both organization and creativity equally may find it difficult to choose between them, resulting in an incomplete picture of their personality. Additionally, forced-choice questions can create false dichotomies, presenting artificial choices that do not fully capture the respondent's true positions.

Why Likert Scales Often Win the Battle
A Nuanced and Comprehensive View
In contrast, Likert scales, despite their own set of challenges, often provide a more nuanced and comprehensive view of a candidate's personality. By allowing respondents to rate their agreement with various statements on a scale, Likert formats capture a broader spectrum of attitudes and behaviors. This granularity can lead to richer data and a more detailed understanding of each candidate. The detailed feedback generated by Likert scales can reveal subtle nuances in candidates' preferences, making it easier to identify the most suitable individuals for specific roles.
User-Friendliness and Higher Completion Rates
Likert scales are also more user-friendly, as many respondents find it easier and more comfortable to express their opinions on a continuum rather than choosing between stark alternatives. This ease of use can result in higher completion rates and more accurate reflections of a candidate's true feelings. The straightforward nature of the Likert scale means that candidates are less likely to feel frustrated or confused, leading to a smoother assessment experience. However, Likert scales are not without their biases, such as central tendency or tendencies to select the most positive response, where respondents might consistently choose middle options or agree with statements regardless of their true opinions.
Flexibility and Detailed Feedback
Despite these biases, the ability to capture subtle differences and provide a detailed picture of personality traits often makes Likert scales the preferred choice in employee selection processes. Their flexibility and detailed feedback can be invaluable in making informed hiring decisions, outweighing the benefits of forced-choice formats in many cases. The comprehensive insights gained from Likert scales can help organizations make more strategic and well-rounded hiring decisions, ultimately leading to a more effective and cohesive workforce.
