Today, let's start by defining risk. What do you think risk means?
I think risk is about the chance of something bad happening.
That's correct! Risk is indeed about the probability of an adverse event occurring over time.
Can you give an example of a risk?
Sure! For instance, driving without a seatbelt is a risk because it increases the likelihood of injury in an accident. Remember that risk can be expressed in both numerical and qualitative ways.
What about perceived risk? How does that change things?
Great question! Perceived risk is how individuals interpret or anticipate risks based on their experiences or beliefs. Understanding both objective and perceived risks is crucial.
Why do scientists sometimes say their reports aren't definitive?
Ah, that's linked to the disclaimer provided by the British Royal Society's report. They emphasize that it's a forum for debate, not a definitive consensus on risk. This illustrates the ongoing disagreements among experts!
Types of Risk

Now, let's dive deeper into the two types of risk: objective and perceived. Can anyone explain the difference?
Objective risk is based on data, right?
Exactly! Objective risk relies on scientific estimations and follows factual data, whereas perceived risk is subjective and differs from person to person.
Can objective data change someone's perceived risk?
Yes! Providing clear data can help shift perceptions. For example, information about the dangers of smoking can help someone recognize the real risks involved.
But what if people still don’t believe the data?
That’s a challenge! Effective communication is essential to mitigate misunderstandings between scientific assessments and public beliefs.
The Role of Data in Risk Assessment

Let's discuss the importance of data in estimating risk. Why do you think data is so critical?
Without data, we can't make accurate predictions!
Precisely! The more data we have, the more refined our risk estimations can be.
What if data contradicts popular beliefs?
That's where clear communication becomes key. It’s crucial that risk managers balance scientific evidence with public perception.
How do we communicate this effectively?
Engaging with the community, simplifying complex data, and using relatable examples can help improve understanding and acceptance.
Bridging the Gap

Finally, let's talk about bridging the gap between objective and perceived risk. Why is this important?
Because it helps people understand real risks better.
Absolutely! Educating the public about scientific truths can help reduce fear and misinformation.
How can we educate them effectively?
Using relatable stories, visual aids, and community engagement can create a more informed public.
So, we talk to them respectfully and share our knowledge?
Yes! Remember, respectful dialogue builds trust and understanding.

Quick Overview
Standard
It highlights the distinction between objective and perceived risks, the role of data in risk assessment, and the ongoing debates among scientists and the general public regarding the concept of risk.
Detailed
Disagreements Among Experts
In this section, we delve into the nuances of risk as expressed by different experts and institutions. The British Royal Society's white paper on risk assessment, published in the early 1980s, serves as a focal point for understanding why experts may diverge in their opinions on the subject of risk. The key takeaway is the differentiation between objective risk, based on scientific evidence and calculations, and perceived risk, which reflects the layperson's anticipation of events.
Risk is defined through the probability of adverse events occurring within a specified time frame. Understanding how to quantify risks involves numerical measures, which can often lead to misinterpretations based on subjective perceptions. The gap between scientific estimations and public perceptions necessitates effective communication to bridge differences. This section emphasizes the need for accurate data to refine risk estimation and discusses the importance of addressing both objective and perceived risks in risk management strategies.

Experts and scientists are called and but disagreement continued about risk.
Detailed Explanation
In this chunk, we learn that despite having many experts and scientists evaluating the concept of risk, there remains a significant disagreement about what constitutes 'risk'. It's essential to understand that risk can be subjective; different people or experts may perceive the idea of risk in various ways based on their experiences and knowledge.
Examples & Analogies
Think of a group of friends discussing the risk of skydiving. Some might say it's a thrilling adventure while others believe it's too dangerous. Each friend's perspective shapes their understanding of the risk involved.

So, actual risk we as scientists saying that we there is actually an actual risk, what is that? So, we are saying that there are 2 kind of risk; one is objective risk that is scientific risk; another one is the perceived risk.
Detailed Explanation
This chunk distinguishes between two types of risk: objective risk and perceived risk. Objective risk is based on scientific evidence and factual data, while perceived risk is how individuals view or anticipate risks based on personal beliefs and experiences. These two types can differ greatly, leading to misunderstandings and conflicts regarding what risks are significant.
Examples & Analogies
Consider a person who believes that traveling by airplane is very risky because they are afraid of heights. This perception may lead them to avoid flying, even though statistically, flying is much safer than driving a car—which represents the actual objective risk.

Now, risk in general, we know the probability of a particular adverse event to occur during a particular period of time.
Detailed Explanation
Risk is defined mathematically as the probability of an undesirable event happening during a specific timeframe. This chunk emphasizes the importance of understanding that risk is not random but instead can be quantified and measured in relation to time and potential consequences.
Examples & Analogies
Imagine planting a tiny apple tree. You know there's a risk it might not grow because of diseases or bad weather. However, by knowing the average growth conditions and probabilities, you can better assess how likely it is to succeed within a year.

Chapter Content
So, determinant of risk; how we determine a risk? Generally, we determine any kind of risk by numerical measures, like expressed in chance of that much cost in dollar or in rupees.
Detailed Explanation
This part explains how risks are measured using quantitative data. By expressing risks in numerical terms, such as financial costs or human lives lost, we can better understand and compare risks. This numeric approach provides clarity and aids in decision-making related to risks.
Examples & Analogies
For instance, if a city calculates that a hurricane could potentially cause $100 million in damages, they can weigh the investment in better drainage systems versus the costs of repairs and lives affected post-disaster.

Now, risk estimation progress; if we want to progress more if you want to refine our estimation, one thing is very clear that we need data, without data we cannot do it...
Detailed Explanation
This chunk highlights the necessity of data in accurately estimating risk. The more data available, the more precise the risk assessments can be. However, it also warns that stakeholder perceptions, which are subjective, should not overly skew disaster risk management plans.
Examples & Analogies
Consider a weather forecast. The meteorologists collect vast amounts of data from satellites and sensors to accurately predict storms. This data-driven approach significantly reduces the uncertainty involved in weather-related risks.

they are saying that it is very important for the risk manager that what scientifically true, and what people think we should reduce that gap...
Detailed Explanation
Here, the focus is on the importance of communicating scientific findings about risks to the public effectively. There is often a gap between what scientists know about risk and what the public believes, and it is essential for risk managers to close this gap for improved disaster preparedness.
Examples & Analogies
For instance, during the COVID-19 pandemic, public health officials had to work hard to communicate why wearing masks was crucial, despite some people perceiving this as unnecessary. Bridging this knowledge gap helped protect communities.
