2023B01 – How different factors in technology-use on audit engagements impact auditor judgment and decision-making

What?

What?

To address these questions we propose two studies, one aimed at each question. In the first project, we examine whether different digital media of communication influence informal advice-giving behavior among auditors. We specifically consider how each medium (laptop versus mobile phone) influences the level of professional skepticism contained in advice. In addition, we look at how the relationship between advisor and advisee influences the way the different media impact skepticism. We expect that the level of professional skepticism in advice will be lower when an advisor is communicating with their mobile phone and that this will be mitigated when an advisor has higher psychologicaldistance from the advice content. This study contributes to existing literature on communication media (e.g., Brazel et al. 2004; Bennett & Hatfield 2013, 2018) as it looks at two forms of digital communication (rather than in-person versus email) and looks at informal advice-giving which adds to our existing understanding of formal advice-giving through the audit review process (e.g., Agoglia et al. 2009).Next, we study the second question, by investigating how an auditor assesses advice received from a hybrid human-technology specialist team, when making judgments related to complex estimates. Specifically, we will examine how the respective roles and collaboration of hybrid team members may influence auditor assessment and reliance on specialist advice. We expect that the level of agreement between hybrid specialists will have different impacts on core auditor reliance, depending on the hybrid specialist workflow. In the advice-literature, convergence has been shown to be preferred to divergence by advisees, however, if an electronic specialist (e.g., AI) is first in the workflow, this convergence could signal over-reliance on technology by a human specialist and thus trigger a core auditor’s algorithm aversion. This study adds to existing research on algorithm aversion of auditors (Commerford et al. 2021) and examines whether such bias can be alleviated by involving a human in the specialist judgment (i.e., making it ‘hybrid’). We further examine whether the level of agreement between the human and electronic specialist’s advice (i.e., advice converges versus diverges) and the order in which the two team members generate their advice influences the auditor’s perception of the quality of the advice and thus reliance on the hybrid specialist team. In addition to extending current literature on algorithm aversion, we also extend specialist advice literature in auditing by examining conditions that influence auditor reliance on specialist advice (e.g., Griffith 2018).

Why?

Investment in technology on audit engagements has increased in recent years and is expected to continue to do so (EY Global 2021, KPMG 2021, PwC 2021, Deloitte 2022). Audit firms are increasingly using technology in their day-to-day work. For instance, there is a recent shift towards remote work, leading to higher reliance on digital communication media (e.g., laptops, mobile phones) for daily auditing tasks and communication. Additionally, there is an increase in efforts to embed more sophisticated technologies (e.g., big data, advanced algorithms) into the auditing process itself. This changing technological landscape can impact auditors’ judgments, decisions, and behavior, and consequently audit quality. In this proposal, we address two questions related to this changing landscape: 1) How does digital communication through different media influence auditors’ judgements? and 2) How does the use of advanced technologies, such as algorithms, for auditing tasks influence auditors’ judgments?

PhD Dissertation: auditor judgments and decisions in the digital era

On 24 February Sara Bibler (in the middle of the picture with Academic Director Anna Gold and COO Klaas Springer of FAR) defended her dissertation about how technology and innovation are becoming increasingly embedded into the auditing process. Data analytics, communication tools, and artificial intelligence shape how auditors perform their work, collaborate with one another, and evaluate evidence. Yet these advancements do not operate in isolation. In a profession with high judgment, such as auditing, quality continues to depend critically on the human auditors who interact with technology. This dissertation examines how auditors’ mindset, the medium through which they communicate, and the mode by which technology is embedded into workflows influence auditors’ professional skepticism, judgment, and reliance. Across three experimental studies, this dissertation highlights behavioral dynamics that emerge in technology-enabled audit environments. The first study shows how cultivating an innovation mindset enhances fraud judgments and supports auditors in balancing audit quality and client insight objectives. The second study demonstrates that the device used in digital communication can shape the way skepticism is conveyed in audit advice. The third study reveals that auditors’ reliance on AI–human hybrid specialist advice is sensitive to how AI is positioned in the workflow and to auditors’ openness to innovation. Together, these studies underscore how certain factors in a technology-driven environment can influence judgments and communication, in turn influencing audit quality.
New technologies like data analytics, artificial intelligence (AI), and smartphones are profoundly changing the work of auditors. Yet, we still know relatively little about how these digital tools influence auditors’ thinking and decision-making. Sara Bibler’s research sheds light on this and shows that not only technology, but especially the interaction between people and technology, determines the quality of audits. Innovative mindset strengthens fraud detection The research shows that auditors who are encouraged to think more innovatively perform better in a data-analytic work environment. They detect fraud more effectively, provide more useful insights for clients, and work more efficiently. According to Bibler, this emphasizes that technological progress alone is not enough: the way professionals think and work plays a crucial role. Smartphone or laptop makes a difference Even seemingly small choices, such as the device used to send advice, appear to have an impact. Advice shared via a smartphone is, on average, less critical and skeptical than advice prepared via a laptop, especially when auditors are deeply engaged in the task. When auditors have more psychological distance from the assignment, this difference largely disappears. This finding suggests that the context in which professionals work can have subtle effects on their judgment. This may prompt organizations to be more mindful of their communication channels in situations where critical judgment is essential. Doubts about AI’s dominant role Bibler further shows that auditors are less inclined to trust advice when AI plays a leading role in audit preparation, compared to situations where AI only plays a supporting role. Auditors with a less innovative mindset, in particular, appear to be hesitant. This means that the way AI is integrated into work processes can significantly determine how effectively this technology is ultimately used. Broad societal impact The results are relevant for accounting firms, supervisory bodies, and policymakers. They demonstrate that audit quality depends not only on technological innovation but also on human factors such as mindset, work context, and trust. For organizations, this means that investing in technology must go hand in hand with attention to training, work processes, and behavior. For supervisory bodies, the research emphasizes that rules and guidelines must consider the human side of digitalization. At a time when AI and digital tools are rapidly gaining ground, the research shows that successful innovation is not just about new systems, but especially about how people work with them.
Audit firms are increasingly adopting mobile communication devices, but their impact on the advice given by supervisors remains unclear. This study examines whether and how the choice of communication device (mobile phone vs. PC) and the psychological distance supervisors feel from the task, affect the advice they give to their subordinates, particularly in terms of enhancing professional skepticism. Using an experiment, we find that mobile phones make skepticism-enhancing advice less persuasive compared to PCs, particularly when supervisors are closely involved in the task. However, when supervisors are more distanced from the task, mobile phones do not significantly reduce the quality of advice and may even enhance certain aspects of professional skepticism. These findings highlight the importance of understanding the behavioral effects of communication tools and being purposeful when making communication choices.
As audit firms increasingly rely on mobile phones for work-related tasks, understanding how different communication devices impact auditor behavior is essential for maintaining professional skepticism and audit quality. Using a setting where an audit supervisor writes a message in response to advice sought by a subordinate auditor, we examine how the audit supervisor’s use of different communication devices (mobile phone versus PC) affects the extent to which their informal advice to the subordinate contains  skepticism-enhancing language. We predict that audit supervisor’s advice will be less skepticism-enhancing or the subordinate when communicated by a message sent through a mobile phone compared to a PC. However, this effect is expected to be stronger for advisors with lower compared to higher psychological distance to the task workflow. We conduct a 2×2 between-participants experiment and use Linguistic Inquiry and Word Count (LIWC) textual analysis to measure skepticism in participants’ responses to advice sought by a subordinate. We find that a message conveyed through a mobile phones compared to a PC contains less skepticism-enhancing advice, but only when psychological distance is low. Our study underscores the behavioral implications of device choice and psychological distance, offering important insights for audit firms and practitioners as they navigate the increasing use of digital communication tools in fostering audit quality.
Abstract: As audit firms increasingly rely on mobile phones for work-related tasks, understanding how different communication devices impact auditor behavior is essential for maintaining professional skepticism and audit quality. Using a setting where an audit supervisor writes a message in response to advice sought by a subordinate auditor, we examine how the audit supervisor’s use of different communication devices (mobile phone versus PC) affects the extent to which their informal advice to the subordinate contains skepticism-enhancing language. We predict that audit supervisor’s advice will be less skepticism-enhancing for the subordinate when communicated by a message sent through a mobile phone compared to a PC. However, this effect is expected to be stronger for advisors with lower compared to higher psychological distance to the task workflow. We conduct a 2×2 between-participants experiment and use Linguistic Inquiry and Word Count (LIWC) textual analysis to measure skepticism in participants’ responses to advice sought by a subordinate. We find that a message conveyed through a mobile phones compared to a PC contains less skepticism-enhancing advice, but only when psychological distance is low. Our study underscores the behavioral implications of device choice and psychological distance, offering important insights for audit firms and practitioners as they navigate the increasing use of digital communication tools in fostering audit quality.  
As artificial intelligence becomes a staple in audit engagements, firms increasingly pair AI with human specialists to tackle complex estimates. But does the way these roles are structured, AI as the preparer or as the reviewer, change how much auditors trust the advice? And can an auditor’s openness to innovation make a difference?
This review explores the following key dynamics:
  • Workflow roles matter. When AI prepares an estimate and a human reviews it, auditors tend to rely less on the advice, driven by algorithm aversion and concerns about overreliance on technology. Conversely, when the human prepares and AI reviews, auditors perceive the advice as more credible and are more willing to challenge management.
  • Transparency and uncertainty. If auditors know AI is involved but not its role, uncertainty amplifies skepticism, further reducing reliance.
  • Innovation orientation as a buffer. Auditors who are more open-minded and comfortable with new ideas, those with a high innovation orientation, are less prone to algorithm aversion and more willing to integrate hybrid advice into their judgments.
The study argues that as AI adoption accelerates, audit firms must consider not only how they assign roles within hybrid teams but also how they foster innovation-oriented thinking among auditors. Doing so can help overcome biases, improve reliance on high-quality advice, and ultimately enhance audit quality.
Although auditors are well-educated professionals, they are also human beings. This means that they are susceptible to judgment biases. Departing from psychological theories, four judgment biases were discussed during Anna Gold’s well-attended masterclass:
  • Availability bias: the tendency to consider information that is easily retrievable from memory as being more likely, more relevant, and more important for a judgment.
  • Anchoring bias: the tendency to insufficiently adjust away from an initial anchor.
  • Overconfidence bias: the tendency to be overconfident in our judgment abilities.
  • Confirmation bias: the tendency to seek and overweight confirming evidence.
It cannot be stressed enough: awareness of the existence of these judgment biases is an important first step in reducing their negative effects.
